How To Make High Power Touch Sensor Circuit

touch sensor circuit

This post describes how to build a High power Touch Sensor using three NPN Transistors. Two TiP3055 Transistors and one BC547 Transistor are used. This Touch Sensor Circuit is powered by a 12V DC Supply. In this you can connect more power load to the output.
