Arduino is at the heart of the circuit as it controls all functions. The input devices we use here are temperature sensor power supply analogto digital converteradc 0804.
Arduino Based Automatic Temperature Fan Speed Controller
Temperature controlled ceiling fan circuit. Simple temperature controlled dc fan circuit is designed with negative temperature co efficient thermistor and an operational amplifier. Here the potentiometer is replaced by the thermistors. We work hard to make. This thermistor variable resistance value based on the temperature when the temperature rises then thermistor resistance gets decrease and for temperature decrease then thermistor resistance gets increase. The basic working principle of temperature controlled dc fan is based on the working principle of the thermistor. Circuit diagram of the temperature fan speed control and monitoring is shown in fig.
Thermistor is temperature sensitive resistor whose resistance changes according to the temperature. Two thermistors r1 and r2 are used to sense the temperature. In this video we have discuss about remote control ceiling fan dimmer. The output devices connected to the micro controller are lcd relay fan. This fan regulator circuit will automatically control the speed of your fan according to the temperature. The thermistor is a component which changes its resistance as its temperature changes.
It is built around arduino uno board board1 162 lcd lcd1 temperature sensor lm35 ic1 and a few other components. Temperature controlled fan circuit in this circuit the temperature sensor used is an ntc thermistor ie. One having a negative temperature coefficient. You can control your room ceiling fan with ir remote. The value of thermistor resistance at 25c is about 1 kilo ohm. Temperature controlled fan circuit operation.
The key component of this temperature controlled fan circuit is thermistor which has been used to detect the rise in temperature. 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 circuit works almost like the published here previously. Digiten wireless temperature controlled outlet digital plug in thermostat outlet with remote control built in temp sensor heating cooling for ac fans heaters remote control detect temperature 35 out of 5 stars 45. 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. The thermostatic feature enables the user to set a desired room temperature range at which the fan will automatically turn on or off.
