proximity detector schematic

Posted on Feb 6, 2014

A very simple proximity detector electronic project can be designed using this schematic circuit. This proximity detector electronic project use a tone decoder integrated circuit ( NE567 ) that will provides a signal with a frequency about 100Khz. When an object is placed near the sensor, the capacitance between sensor is increased. The Q1 and

Q2 transistors will amplify the signal and fed it to the NE567 IC, that will make the LED1 to glow.
