Description

Circuit diagram like in figure 1 above is Circuit Diagram Fire Alarm System using Thermistor and NE555. According Circuitstoday site describe that 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.

Description

Circuit diagram like in figure 1 above is Circuit Diagram Remote Control using VHF Modules, NE555 and 4017 IC. According ElectronicZone site describe that A few designs for remote control switches, using VG40T and VG40R remote control pair, are shown here.

The miniature transmitter module shown in Fig. 1, which just measures 34 mm x 29 mm x 10 mm, can be used to operate all remote control receiver-cum-switch combinations described in this project. A compact 9-volt PP3 battery can be used with the transmitter. It can transmit signals up to 15 metres without any aerial. The operating frequency of the transmitter is 300 MHz. The following circuits, using VG40R remote control receiver module measuring 45 mm x 21 mm x 13 mm, can be used to:
(a) activate a relay momentarily,
(b) activate a relay for a preset period,
(c) switch on and switch off a load.

To activate a relay momentarily (see Fig. 2), the switch on the transmitter unit is pressed, and so a positive voltage is obtained at output pin of VG40R module. This voltage is given to bias the relay driver transistor. The relay gets activated by just pressing push-to-on micro switch on the transmitter unit. The relay remains energised as long as the switch remains pressed. When the switch is released, the relay gets deactivated. Any electrical/electronic load can be connected via N/O contacts of the relay.

To activate a relay for a preset period (refer Fig. 3), the switch on the transmitter unit is pressed momentarily. The transistor gets base bias from VG40R module. As a result the transistor conducts and applies a trigger pulse to IC 555, which is wired as a monostable multivibrator. The relay remains activated till the preset time is over. Time delay can be varied from a few seconds to a few minutes by adjusting timing components.

Description

Circuit diagram like in figure 1 above is Circuit Diagram Portable Power Inverter using CD4047 IC. According Electroschematics site describe that the circuit is built around the monostable/astable multivibrator CD4047 (IC1). The resistor (R2) and capacitor (C3), connected to pins 2 and 3, will decide the frequency of the astable output pulses (here, it is at about 50 Hz). IC1 gives two similar frequency outputs at pins 10 and 11 (phase of the Q and Q signals varies about 180 degrees). The square wave output signals are processed by the two-channel transistor banks (T1-T3-T5 and T2-T4-T6) to drive the power transformer (TR1). In my prototype, TR1 is a 60-VA toroidal transformer with a nominal 12-V rms secondary and 5-A current. I have powered up the inverter with an SMF battery of 12 V close to 7 Ah and successfully powered one 230-V/40-W lightbulb. The efficiency looks promising with neither the MOSFETs nor the transformer getting hotter than warm.
