What is Overview of Smoke Sensor Types about?
There are two main types of smoke sensors: MOS and photo electric. MOS sensors like the MQ2 use a voltage divider circuit to detect concentrations of gases like smoke, but cannot identify the specific gas. Photo electric sensors like the RE46C194 use an infrared light source and photo amplifier to measure light levels and compare the difference between light on and off readings to detect smoke. If smoke is detected over three consecutive checks, the sensor will go into alarm mode, activating the horn and se
