Hi guys, i would to build a small temperature controller project using microcontroller (PIC), a temperature sensor(lm35) and a on/off relay.
But i dun really know how to do a PID control using a relay as it cant really be applied with the PID equations.
Can anyone show me the methods? or some explainations on how to adapt the equations to on and off the relay to stabilize at the setpoint temperature.
If possible, i need autotune for this method as well(using relay), thankx.....
