contactless electric line tester- detect the line when the sensor wire touched over the cover of wire

non-contact electric tester circuit

overheat or temperature sensor– adjust the preset to what level of temperature do you want to automatically detect. You get a signal from the buzzer when cross the heat to a fixed level. This circuit can be used in an automatic controlling circuit to preventing a device to damage from overheat. 

This delay timer is very easy to make – This is very useful to prevent a device from sudden unregulated voltage spikes or surge current. you can change the delay time duration by changing the value of capacitor C1. When a 220uf capacitor used duration of delay is about 5 – 8 seconds.

on delay timer circuit

This is another electric tester circuit that detects the signal from touching the sensor wire over the cover of wires. Use only Battery for this circuit.

Hi, My name is Aman Bharti, I am interested in making and study of Electronics, circuit diagram, PCB designing and layout etc. I like to share the knowledge and all ideas with people which I get from My Experiment & from different sources. I try to provide any circuit details deeply with test results as possible. If you want to give a suggestion or comments on anything, please leave your comment in the comment box of the related page.
