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.
