GYM Touch Sensor Switch Circuit for school/College Projects | Single wire Touch Switch with Sensitivity Control and Output Relay Module Kit Educational Electronic Hobby Kit

It is a single wire activated touch switch. When we touches at the tip of the wire, then the circuit gets ON and activated the output relay and it stay in ON condition. When we touch again it deactivated the relay and stay at OFF condition. So we can easily connect any type of load to the output relay. So we can use it as touch controlled light, touch controlled fan, burglar alarm, etc... The input is highly sensitive. The PCB is fully assembled and high quality. The circuit is designed and tested by engineers. It is works from ordinary 9V battery. NOTE: No battery included.
