Sensors: Different Types of Sensors

· Non contact Sensors – This type of sensor does not require any physical contact with the object or media that is being sensed. They supervise non-reflective solids and liquids but are not useful for gases due to natural transparency. These sensors use Plank’s Law to measure temperature. This law deals with the heat radiated from the source of heat to measure the temperature. Working of ...

Pressure Sensor Guide -

The pressure sensor module has a publicized measurement range of psi. The unit psi is an imperial measurement which stands for pounds per square inch. If the psi unit is converted to the SI unit Pascal (PA), then measurement range of the pressure sensor denotes 0-40 kpa (1 psi is equal to about Pascal).
