AUTOMATIC TEMPERATURE BASED FAN SPEED CONTROL SYSTEM Circuit Diagram

AUTOMATIC TEMPERATURE BASED FAN SPEED CONTROL SYSTEM Circuit Diagram A fan controller schematic refers to the circuit diagram or design of a fan controller. It outlines the components and connections required to build the fan controller. Advanced features: Pre-made fan controllers often come with advanced features such as temperature monitoring, automatic fan speed adjustment, and fan failure detection

This is automatic fan controller circuit project. When sensor system gets hot, this will control speed motor fan is highest. It uses a few components and easily buys at local markets. And easy to build with small PCB. Also, you can modify it to more controls anything as you need with contact of the relay.

Automatic Temperature Control Fan Speed Circuit Diagram

The analysis controller performance in terms of automatic temperature control based on the speed of the ac fan. temperature controlled ac fan regulator include a diac, triac, 220 power supply and a sensor for sensing the temperature of the environment or device, and a control unit being configured to collect data during the operation of the

The thermistor used in the circuit here, decreases its resistance with increasing temperature, hence the electrical conductivity also increases, increasing voltage across it, resulting in an increment in the speed of the fan. Thus, it is possible to control the speed of the fan automatically when the device's temperature varies. Here the code given is based on the D11 pin as an output. Whenever the temperature sensor detects the changes in temperature outside the Arduino varies the PWM output at the D11 pin, hence the speed of the fan varies. Further in this circuit, the SL100 transistor acts as a switching transistor. And we need a 12V power supply to bias the circuit.
