Temperature Controlled Ceiling Fan Circuit

The circuit consists of a four element balanced bridge a transistor imbalance detector and a single transistor power amplifier for driving the fan.

Temperature controlled ceiling fan circuit.

The input devices we use here are temperature sensor power supply analogto digital converter adc 0804. Two thermistors r1 and r2 are used to sense the temperature. This change is reflected on the fan speed by regulating the current to the fan s motor. The output devices connected to the micro controller are lcd relay fan.

The remote is able to control the speed of your fan as well as control the lights of the ceiling fan with on off and dimming options.

Working of temperature controlled dc fan using thermistor. My temperature controlled fan circuit has a liquid crystal display connected to the arduino to display the temperature in celsius and fan speed 50 255 pwm this controls the duty cycle of the fan which then controls the fan speed.

This project temperature sensor based ceiling fan control system mainly explains you about the use of a fan with out the help of regulators. The hampton bay universal thermostatic ceiling fan remote control adds ultimate functionality to your ceiling fan. It features 3 fan speeds high medium low and includes a full range light dimmer. In this circuit pin 3 non inverting terminal of op amp 741 is connected with the potentiometer and pin 2 inverting terminal is connected in between of r2 and rt1 thermistor which is making a voltage divider circuit.

Some may recall tech school experiments that employ galvanometers as bridge imbalance detectors. Schematic of the temperature controlled fan circuit. The westinghouse thermostat ceiling fan and light remote control automatically turns your fan on and off and sets the fan speed based on room temperature.

The thermostatic feature enables the user to set a desired room temperature range at which the fan will automatically turn on or off. This fan regulator circuit will automatically control the speed of your fan according to the temperature. The circuit works almost like the published here previously. The output from sensor is directly.

It works on the principle of thermistor.
