Hi Electronics Geeks!
I am working on TEC temperature controller using ATmega32 MCU. Thermistor of 10K is interfaced and the Steinhart-Hart Thermistor Equation is applied to get the temperature reading using ADC.I am getting correct reading with little Fluctuations.The other part of the project is to set the desired temperature and achieve that by heating/cooling the peltier plate(TEC12706) with below specification,
Model number: TEC1-12706
Voltage : 12V
Vmax (V) : 15.4V
Imax (A) : 6A
QMax (W) : 92W
Nominal Power : 60W
Internal resistance: 1.98 Ohm +/- 10%
Dimensions : 40mm x 40mm x 3.6mm
I have read that PID is the method to achieve the result but dont know how to implement.I can generate PWM signal to control the H-bridge voltage.
Can you help me in below part?
1)How to implement PID in ATmega32 or code?
2)H-bridge Design using MOSFET for TEC1-12706?
Thank you for reading.
