Different Types of Sensors and their Working

20210409· Its main principle is when the junction of two different metals are heated or exposed to high temperatures a potential across their terminals varies. So, the varying potential can be further used to measure the amount of change in temperature. Strain Gauge (Pressure/Force Sensor): A strain gauge is used to detect pressure when a load is applied. It works on the principle of resistance, we know ...

Gas Sensor an overview | ScienceDirect Topics

This increases the cost even further (well in excess of 100). The current gas sensor market has been estimated to be around 500 million per year and growing at a rate of 10% per annum (MNT Gas Sensor Roadmap, ). However, the growth in the market in recent years has been achieved by lowering the unit cost of sensors through the development of smaller gas sensors. Further growth will be ...
