This circuit is for 12 V batteries but can be used with batteries of other voltages by changing the zener diode. The trigger point is adjusted by R1. The operating system accepts equivalents.
The presence of a low resistance between the terminals of the sensor causes this modulated...
The frequency of this oscillator depends on R and C (see math section for electronics). The...
