PID temperature controller with on/off and lm35 sensor

[cpalka]

Dear all

recently I research for a program that can control the temperature with PID.

Many programms with analogue output from 0-5v like to control a dc motor for example.

I needed a analogue output (PWM) to open or close the rele that arms the heater, but controlled by the pid.

My program works with NI6008, a 5v rele, heater and one lm35 temperature sensor.

So if you need to control the temperature in a room or oven, here is the good example.

I set the point 60, but when I run this program ,it stopped at 50 .😥
