7 Best Touch Sensor Switch Circuits Explored
In this post I have explained 8 easy methods of building touch sensor switch circuits at home, which can be used for switching 220 V appliances ON/OFF with mere finger touch operat ions. The first one is a simple touch sensor switch using a single IC 4017, the second one employs a Schmidt trigger IC, […]
Make this Touch free Faucet Circuit for Hands-free Tap Control
A very simple touch free faucet circuit or touch free automatic tap circuit can be built using as little as an IC 555 and a few passive components, in order to implement a contact less water supply operation from the attached facet or the tap. Drinking Water is Precious Pure drinking water which we normally […]
Make this Thermo-Touch Operated Switch Circuit
The circuit explained here employs a rather different approach for implementing a touch operated switch action. Here instead of the resistance, the warmth of the finger is used for sensing and operating the circuit’s output. Irrespective of the ambient conditions, our hands and fingers mostly exhibits some extra warmth or increase in the level of […]
