STEVAL-IHM037V1
Ceiling fan remote control unit based on the STM8 microcontroller
Data brief
Features
• Operating voltage: 180-250 VAC
• Low-cost capacitive power supply for the
STM8S003F3 (receiver), and CR2032 coin cell
battery for the STM8L101F2 (IR remote)
• Triac-based speed control with firing angle
• IR receiver for speed control through RC5
remote
• Two pushbuttons for speed change
• RoHS compliant
Description
The STEVAL-IHM037V1 demonstration board
implements speed control for an induction motorbased ceiling fan using a remote control.
Traditionally, fan speed is controlled using a Triacbased 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.
