Hi all, this is my first post.
I want to make a circuit that measures water temperature, at 70c it will switch a heater on and at 80c it will switch off and i want to run it from a 6v or 12v battery.
Is this possible?????
I suggest one of the digital temperature sensors. No need to mess around with analogue.
Thankyou ron,
The bulb is 55watt. Can you put the J type thermocouple directly into water?
I Have no experience programming or using micro-controllers but will begin research.
I want to do this project as cheap as possible.
