I'm pretty sure the Peltier will degrade if on/off hysteresis is used, due to thermal cycling. The issue I am having at the moment is working out how to measure the temperature of the side of the peltier module that is in contact with the surface I am regulating. 5. It needs to have relatively precise temperature control, but nothing too fancy, a resolution of +/- 1C is fine with me. My problem comes to the power circuit connected to the Peltier, I will use a 37. 4V Oct 10, 2014 · If you want more precise temperature with faster response, maybe peltier with MOSFET transistor control would be better option, but it's little out of the your question Related topics Topic Oct 15, 2022 · A PID arduino controller for a peltier for temperature precise control. This avoids hysteresis. Dyrtull April 12 (temp); return temp; } //Temperature control on the peltier by using the measurements as reference float TempControl (float target Mar 7, 2017 · This is my first time to use Peltier as well as PID control. This can easily be switched by an Arduino's digital output or controlled with PWM (Pulse-Width Modulation) to increase or decrease the rate of temperature change in the Peltier. npjmsfp wtk yivkx ftvp wqmxyqkn yxsnq mecorj lexzi dmju ljcx
