3 Simple Proximity Sensor Circuits

+

InfraRed (IR) Sensor/Detector Circuit. The IR circuit described below is mainly designed for liquid level detection or proximity detection. The IR sensors used here are an IR LED and an IR photo diode. The circuit operates by detecting the distance from the target by reflection of an infrared beam. The biggest advantage of this circuit is that there is no physical contact with the liquid whose level is to be …

Although the entire IR spectrum can be used as a fingerprint for the purposes of comparing molecules, the 600 1400 cm1 range is called the fingerprint region. This is normally a complex area showing many bands, frequently overlapping each other. This complexity limits its use to that of a fingerprint, and should be ignored by
