Description

Circuit diagram like in figure 1 above is Circuit Diagram Interfacing SPD005G Pressure Sensor to Arduino UNO. The pressure sensor used here is SPD005G from Smartec . SPD (Smart Pressure Device) is a series of silicon based pressure sensors suitable for industrial as well as house hold applications. These sensors are generally available in plastic inline or dual inline packaging. SPD sensors are generally available in two operation modes namely gauge type and absolute type. In gauge type the pressure is measured with respect to the atmospheric pressure. There is  a small vent on the package for getting contact with the atmosphere. In absolute type, the pressure is measured with respect to vacuum. A small vacuum chamber is incorporated into the package during fabrication. Typical applications of SPD005G are medical systems, BP monitoring, air conditioning systems, process control, hand held pressure sensors  etc.

The sensor used here ie; SPD005G is a gauge type sensor. There are actually four sensing elements inside the SPD005G and they are arranged like a Wheatstone bridge. The sensing range of SPD005G is 0 -  0.350 x 105 Pa ( ie; 0 – 14.50 psi).
