Temperature Sensor

The temperature sensor is based on the LM35 Temperature IC. The IC is soldered onto a small piece of veroboard together with its de-coupling capacitors. This small temperature module is then fastened to the MOSFET heatsink and the the sensor leads are connected to the PWM Micro Processor as shown in the controller circuit diagrams. The location of the temperature sensor is shown in the pictures below:
