Hi all,
I am planning to design a hardware circuit to test electric underfloor heating (ideally without a lcd display or the use of a microcontroller)
The inputs to the system will be LIVE, NEUTRAL, EARTH (not live).
The resistance of the cable between LIVE AND NEUTRAL should not fall below 1Mohm
If it falls below 1Mohm i want my circuit to alert me by a buzzer or LED. But how can i design a system to trigger a ON state if it falls below 1Mohm. Output needs to be either ON or OFF (ie not a half lit LED)
All suggestions welcome,
Thanks in advance!
