Digital Temperature Sensor GQQ0.1 Smoke Sensor

Application&Introduction

GQQ0.1 ( original model KGQ-1 type ) smoke sensor is mainly used for coal mine rubber, coal dust from the heat due to friction or other causes fumes to be monitored. The sensor uses advanced gas sensing probe , through a special circuit processing . Sensitive,reliable, and correct move, without tripping characteristics. Shell small size, easy to use , is the ideal smoke alarm installed components.

Working principle:

Connect the power , its green light , to be stable after 10 minutes , the green off red light, said detection probe thermal stabilization time ends , the sensor into the detection state. When a small amount of smoke into the smoke chamber , the red light flashes , while controlling three conduction , the output low , smoke fault indication light, the relay is closed. Achieve automatic fire protection or smoke . Meanwhile speaker "X number belt smoke " language police. Host achieve protection and lockout, this time to restart , need troubleshooting, and click the Stop button to unlock , and then press the start button , belt drive to run from the car .
