Product overview
Description
The STEVAL-IHM037V1 demonstration board implements speed control for an induction motor-based ceiling fan using a remote control. Traditionally, fan speed is controlled using a Triac-based regulator, which must be operated manually.
The STEVAL-IHM037V1 replaces the manual regulator with a remote control-based solution. Two pushbuttons are also provided to increase or decrease fan speed. Speed is regulated by controlling the firing angle of a Triac (T435x) with the STM8S003x microcontroller.
