I just found these two (1,2) low power consuming Peltier elements that I would like to include them to my project. What I'm planning to do is to drive them until to reach some specific temperature e.g 60-90 Celcius (using some kind of PID).

Since they consume so little power, I thought that they might be able to be controlled with a simple transistor/MOSFET but I don't really know how exactly to choose the proper one.

Any idea on which one to choose? Also, I would be interested (if one has time to write it down) to see the whole pipeline you follow to choose a proper one.

Thanks.

    This will probably get flagged as it has nothing to do with raspberry pi. A better place to ask might be electronics.stackexchange.com Or google "Drive a 1A load with Mosfet" and you will find examples. Just make sure what ever MOSFET you select can be driven with 3.3V

  • @J.Doe If your goal is to heat something up, you should really use a power resistor, not a Peltier element, unless by "reach some specific temperature e.g 60-90 Celcius" means you want to cool something down to 90°C. Nov 29, 2018 at 14:18
