Arduino ac fan speed control.
Temperature based fan speed control using arduino and lm35 sensor by muhammad ansar.
The microcontroller controls the speed of an electric fan according to the requirement allows dynamic and faster control and the lcd makes the system user friendly.
We previously used pwm techniques in many projects.
If you just want to switch the fan on off based on the data provided by dht 11 then a 220v relay should suffice.
In theory it should work to control the speed of fan.
In this post we have described how to design temperature based fan speed control monitoring with arduino and lm35 temperature sensor.
But if you want to controller the speed depending upon the humidity and temperature you will require a li.

I bought one and tested.
Programming the arduino for ac fan speed control.
One of the pictures shows on the backside of the module that it is for 2 a 5 a peek.
The manufactures description mentions fan regulator.
Ac ceiling fan speed control using arduino uno r3.
The module gives you a basic circuit to control ac.
This should be good for 230 v 100 w motor.
Yes you can very well can.
But i didn t had this chip and to see the rpm i had to make a tachometer.
