I want make Project Heater for mcu. I want control Temperture by switch up/down.
I try it not stable .how i can control?
 

Hi, "sod-ru-sod-hen" or "yak-roo" you can try this MAX6675, but can not order free sample from Maxim.
 
you can use PWM on MCU to control output driver for the heater, and ADC to monitor the temperature sensor


Regards,
 

well , to control a heating system is not an easy thing, especially you want an accurate temp.
A closed-loop system is essential, and try some arithmetic like PID.
it usually take a long time to get a steady system:)
 

how to interface the controller and the heater?
 

To interface microcontroller and a load (heater, for example) you can use an optocoupler and a triac .. see picture below ..

How I adap PID to Heater? I use Themister to measure Temp. What is Solution ? about Temp, Time and Power (PWM).
