GP2Y1010AU0F Dust Module Features The GP2Y1010AU0F is an optical air quality sensor, designed to sense dust particles. An infrared emitting diode and a phototransistor are diagonally arranged into this device, to allow it to detect the reflected light of dust in air. It is especially effective in detecting very fine particles like cigarette smoke, and is commonly used in air purifier systems. You can download the datasheet of this module here.[wpdm_package id='18191'] ...

PC817 Optocoupler Module Features An Optocoupler, is an electronic component that interconnects two separate electrical circuits by means of a light sensitive optical interface.There is a is a light emitting diode with a phototransistor inside the optocouplers, both of them are isolated from the external environment of the optocoupler; This means that the internal phototransistor can only receive light emitted by the internal light emitting diode. The phototransistor base is stimulated by light receive...

TLP281 4-Channel Opto-isolator IC Module Features Sometimes we need to separate the low-voltage section (microcontroller) from the high-voltage one in circuit in order to prevent noise and damage to the microcontroller. This module isolates the low-voltage section from the high-voltage section using TLP281-4 IC. This IC contains 4 LEDs (Light Emitting Diode). 4 high-voltage channels can be controlled by microcontroller using this IC.This module can also be used to turn on and off the servo motor and oth...
