Circuit Diagram 

Component Part


Description

Circuit diagram like in figure 1 above is Circuit Diagram Three in One Temperature Sensor Shield for Arduino Nano. According Electronics-lab site describe that this 3 in 1  shield for Arduino Nano helps to develop various temperature measuring applications. Arduino Nano shield consists of 3 different types of temperature sensors.

  1. MLX90614 non-contact temperature sensor
  2. 10K NTC Analogue Temperature Sensor
  3. Programmable Resolution 1-Wire Digital Thermometer

MLX90614

The MLX90614 is an infrared thermometer for non-contact temperature measurements. Both the IR sensitive thermopile detector chip and the signal conditioning ASIC are integrated in the same TO-39 can. Integrated into the MLX90614 are a low noise amplifier, 17-bit ADC and powerful DSP unit thus achieving high accuracy and resolution of the thermometer. The thermometer comes factory calibrated with a digital SMBus output giving full access to the measured temperature in the complete temperature range(s) with a resolution of 0.02°C. The user can configure the digital output to be pulse width modulation (PWM). As a standard, the 10-bit PWM is configured to continuously transmit the measured temperature in range of -20 to 120°C, with an output resolution of 0.14°C.

DS18B20

The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. In addition, the DS18B20 can derive power directly from the data line (“parasite power”), eliminating the need for an external power supply. Each DS18B20 has a unique 64-bit serial code, which allows multiple DS18B20s to function on the same 1-Wire bus. Thus, it is simple to use one microprocessor to control many DS18B20s distributed over a large area. Applications that can benefit from this feature include HVAC environmental controls, temperature monitoring systems inside buildings, equipment, or machinery, and process monitoring and control systems.
  1. Measures Temperatures from -55°C to +125°C (-67°F to +257°F)
  2. ±0.5°C Accuracy from -10°C to +85°C
  3. Programmable Resolution from 9 Bits to 12 Bits
  4. Supply 5V DC
  5. Output Data pin Connected to Digital Pin D12 of the Arduino Nano
NTC 10K with 10K Divider Resistors

NTC stands for “Negative Temperature Coefficient”. NTC thermistors are resistors with a negative temperature coefficient, which means that the resistance decreases with increasing temperature. Thermistors are low cost accurate components that can be used as temperature sensing device for various applications. The NTC is connected to Analog A0 of Arduino Nano pin with 10k divider Resistor.

How to Choosing the Best Impect Driver in a Tool using Motor

Robotronicdiagram. - This is one of the information for you who want to know more about the best impect driver in a tool using motor like drill and others with the article tittled How to Choosing the Best Impect Driver in a Tool using Motor that published in Protool Review site.

Once in a while a tool comes along that makes us wonder how we ever lived (or at least worked!) without it. Just about every tradesman would agree that the cordless impact driver falls into that category. For decades, we tried to squeeze enough torque from our drills to drive long fasteners into hard materials. And getting a drill to budge an old, rusty screw or bolt? Not easy. There were a lot of half-sunk screws or rounded-out heads in those days. It was a problem of torque – getting enough rotational force – to make the turn. Regular drills rarely had the chops to do the harder jobs – at least without significant stress to the tool or fastener. Viable cordless impact drivers came along in the early 2000s and our work has never been the same. If you don’t have one, we suggest you get one! Here’s what to look when choosing the best impact driver.

Choosing the Best Impact Driver

Motor

First, consider impact drivers with brushless motors. Brushless motors are more expensive then their brushed motors counterparts, but they have longer lives and require less maintenance. Moreover, brushless motors run more efficiently, produce less heat, and support smart electronics. Smart electronics, or smart tools, are general terms we use to describe tools whose battery and motor communicate to optimize performance and prevent thermal overload. Smart electronics also allow even higher tech features like Milwaukee’s One-Key or DeWalt’s Tool Connect. It’s not the end of the world is you go with a brushed motor, though. You’ll save money and still get Pro-level performance, but give up some benefits.

Voltage

Impact drivers are available in both 12V and 18V versions. By way of torque comparison, 12V impact drivers generally match the inch-pounds of torque found in 18V drills. You’ll get several hundred more inch-pounds from 18V Impact Drivers. We’ll talk more about torque below. It’s very likely that you’ll be able to do 80% of your job with the smaller and lighter 12V tool, but for the Pros or anyone else needing some extra muscle, 18V is the way to go.

How does the Radio Frequency Identifier (RFID) work?

Robotronicdiagram. - Radio Frequency Identifier or usually called with RFID in this time has been using in many field to make easy people in their life. RFID can be connected with Internet of Things (IoT) to build integrated smart city and other in it application now. But, do you know how the RFID work now?

In this time we will discuss how the RFID work that we hope will give you many advatages knowledge about this RFID to your project next.

Accordingly Circuitstoday site describe that the RFID chips are made to be small, as they do not need any power source. It needs an RFID tag to work. The RFID tag comprises of antenna and chip. This tag needs to come in contact with an RFID reader, for it to work.

In case of an RFID enabled credit card, one can access the details of the card like the name, card number etc., if it comes in contact with an RFID reader. However, the tag must be in a specified distance from the RFID reader. This distance depends on factors like power, frequency, antenna size etc.

Since this makes the card vulnerable to misuse, credit card companies take various measures to ensure it is safe from the hackers and criminals. However, you can always ask your bank for a card without RFID if you are sceptical about the safety. Also, covering the RFID enabled card in a foil is a sure shot way of blocking the wireless signal or you could just take out the chip by yourself.

However, when it comes to everyday use, these methods may not seem practical.

Nowadays, there is another way of making sure your RFID credit card is safe. Wallets capable of blocking these RFID signals are now available in the market.

Even though RFID credit cards give you the advantage of saving time during the checkout, making payments easy and hustle free, it does have a downside.

RFID skimmers are used by hackers and criminals to access your credit card. All they do is use an illegitimate RFID reader in a distance that scans and downloads all the information from the card. This form of digital theft is known as RFID skimming. Using the information these hackers/thieves duplicate your card and leave you with a zero balance in your account.

Since RFID is nothing but electromagnetic waves, blocking it is very easy. Going for an RFID blocking wallet is the best option you have.

SUSU Scientist Invents Electric Motor for Aerospace Equipment by Sputnik News

Robotronicdiagram. - This is one of the information for you who want to know more about electric motor in this time with the article titled SUSU Scientist Invents Electric Motor for Aerospace Equipment that published in Sputnik News site.

Image Courtesy of https://sputniknews.com

A team of scientists and engineers from the Polytechnic Institute of South Ural State University within Project 5-100 invented useful brushless electric motors for aerospace equipment.

The operating principle of such a motor is the following: a system of constant highly efficient magnets of rare-earth elements is placed on the spinning part of the motor – the rotor; a system of conductive coils is placed on a stator. When switching current in these coils, the magnets start pursuing the traveling field and lug the rotor along.

These results had been achieved due to the use of a compacted engine configuration provided by 3D print technology for producing electric coils made of a light metal alloy with a current distributor of a variable cross-section. Engineering solutions used in the motor’s construction are presently being patented.


One of the advantages of the electric motor is its reliability. When comparing the number of details composing a combustion engine and an electric motor of the same capacity, it is noticeable that the latter only has two components: a rotor and a stator. A piston engine has several times more moving components. When combining the use of electric motors and highly efficient electric energy sources, electric traction starts overtaking other engines by its characteristics, first of all, by its reliability.

Circuit Diagram Fire Alarm using Thermistor and NE555

Robotronicdiagram. - This is one application of thermistor and NE555 to make you easy to build firm alarm in this time.

In this article, we will show you the circuit diagram of Fire Alarm using Thermistor and NE555. Beside that we also will show you the component parts and the global description of this circuit diagram according the original source description. 

Circuit Diagram 

Component Part
  1. Resistors
  2. Thermistor
  3. Capacitors
  4. Transistors
  5. NE555 IC
  6. Speaker
Description

Circuit diagram like in figure 1 above is Circuit Diagram Fire Alarm using Thermistor and NE555. According Circuitstoday site describe that many fire alarm circuits are presented here,but this time a new circuit using a thermistor and a timer to do the trick. The circuit is as simple and straight forward so that, it can be easily implemented. The thermistor offers a low resistance at high temperature and high resistance at low temperature. This phenomenon is employed here for sensing the fire.

The IC1 (NE555) is configured as a free running oscillator at audio frequency. The transistors T1 and T2 drive IC1. The output (pin 3) of IC1 is couples to base of transistor T3 (SL100), which drives the speaker to generate alarm sound. The frequency of NE555 depends on the values of resistances R5 and R6 and capacitance C2. When thermistor becomes hot, it gives a low-resistance path for the positive voltage to the base of transistor T1 through diode D1 and resistance R2. Capacitor C1 charges up to the positive supply voltage and increases the the time for which the alarm is ON. The larger the value of C1, the larger the positive bias applied to the base of transistor T1 (BC548). As the collector of T1 is coupled to the base of transistor T2, the transistor T2 provides a positive voltage to pin 4 (reset) of IC1 (NE555). Resistor R4 is selected s0 that NE555 keeps inactive in the absence of the positive voltage. Diode D1 stops discharging of capacitor C1 when the thermistor is in connection with the positive supply voltage cools out and provides a high resistance path. It also inhibits the forward biasing of transistor T1.
