This is a transducer pressure sensor used for Fuel / Gas / Oil / Liquid / Water and Air. A pressure sensor is a device that express the force from expanding, usually acts a transducer that generates a signal as a function of the pressure. Pressure sensor are commonly used for control and monitoring and also be used to indirectly measuring other variables such as fluid, liquid, gas flows, speed, water level, and altitude. This device is alternatively named pressure transducers, pressure transmitters, pressure senders, pressure indicators, piezometers, manometers. As an example to this project we will going to build a valve with LCD display to see the value comes from the sensor and process and controlled by our microcontroller. This sensor is running on 5v VDC at ≤10 mA, pressure range to 0 ~ 1.2 MPa at 2.4MPa Max > Note: 3.0 MPa will damage the sensor.
