Good Day!
My team's working on a fermenting device.
It's supposed to produce a constant temperature but it's not necessary to stay like that all the time.
The device must be able to produce 37 degree Celsius using 3.5 to 9 volts.
After reaching the desired temperature, an allowance of maybe 2 to 3 degree Celsius is allowed then the source will automatically "Turn-off".
Once it reached 2 to 3 degrees less than 37, the device will automatically turn on again.
We're thinking of using a nichrome wire to produce the desired heat but we're still looking for other materials.
The heating material will be placed inside a vaccum.
I understand that this kind of project would need a thermostat but I still don't know where to start.
I tried comparing it with the operations of rice cookers but those need water in order to maintain constant temperature.
So, 1.) How can one maintain a constant 37 degree celsius using 3.5 to 9 volts? (minimal temperature discrepancy/tolerance is allowed)
2.) What kind of heating material is best for such project?
3.) Are there any other approaches that could yield the same function?
My english isn't very good but I hope I was able to state my case as simple and as precise as possible.
