HVAC Thermostat : Temperature Control

Thermostat are widely used in industries and big residential buildings and are usually used to sense the temperature of the system and maintained it. Thermostat plays very important role in air conditioning and ventilation and HVAC thermostat are widely used in industrial buildings to sense and control the temperature. This thermostat project will focus on the heating control of a space that uses electric heater as its source of heating. This project will composed of a comparator that controls the ON and OFF of the electric heater based on the sensor temperature.

As shown above the circuit diagram of this project contains resistor, thermistor, heater, potentiometer, transistor, Op-Amp etc. Potentiometer is used to calibrate the circuit and Operational amplifier is used as comparator to sense the inputs of the reference voltage (PIN 3) and room temperature (PIN 2). The thermistor used is a NTC (negative temperature coefficient) type where its resistance will drop when the temperature increases and vice-versa. Use this report for your reference and study only.
