Ac led light dimmer module.
The circuitry which is linked to the microcontroller via the signal input header h1 drives an optoisolator triac driver oc1.
This module contains a triac triggering coupled with zero cross detector mechanism for programming the intensity of incandescent lamps led dimmable bulbs heating elements or fan s.
Compatible with any arduino raspberry and other mcu.
Ac light dimmer module 1 channel 3 3v 5v logic ac 50hz 60hz 220v 110v buy at lowest price from amazon this module works on pwm pulse width modulation control in simple words we decrease or increase the duty cycle to set the intensity of the led.
Ac light dimmer module controller arduino raspberry compatible 50 60hz 80 240vac auto detect ac line frequency 50hz or 60hz.
Pwm is also used to.
So our goal is to control the ac dimmable led bulb automaticaly to dim itself using the light sensor module as the potentiometer so that as the light varies the ac dimmable led bulb will dim as the light start to increase or decrease.
Module contains a triac triggering coupled with zero cross detector mechanism for programming the intensity of incandescent lamps ac led dimmable bulbs heating elements or fan speed controlled.
Module contains 8 triacs with zero cross detector for programming.
Device can be controlled via variable resistor.
The ac light dimmer module circuit it is clear from the circuit diagram that the key component of the design is a standard triac tr1.
