คำอธิบาย
เซนเซอร์ก๊าซ คาร์บอนมอนอกไซด์ MQ-9 Carbon Monoxide (CO), Flammable gasses Sensor
Technical Parameter
- ตรวจจับแก๊ส คาร์บอนมอนอกไซด์ Carbon Monoxide (CO), Flammable gasses
- ตรวจจับความเข้มข้น Detection Range
- Input voltage: DC5V
- Sensitive material MQ-9 gas sensor is used to clean the air in the lower conductivity of tin dioxide (SnO2).
- Detection method using low temperature cycling (1.5V heating ) to detect carbon monoxide, conductivity sensors with carbon monoxide in the air increased with increasing gas concentration , spurious adsorption at high temperatures (5.0V heating ) detection of combustible gases methane, propane and cryogenic cleaning gases.
- Simple circuit can be used to change the conductivity , concentration of the gas is converted to the corresponding output signal.
- MQ-9 high gas sensor for carbon monoxide, methane , liquefied petroleum gas sensitivity , the sensor can detect a variety of gases containing carbon monoxide and flammable , is a low-cost sensors for a variety of applications.
Application:
- Domestic Carbon Monoxide (CO), Flammable Gas concentration detector, Industrial Carbon Monoxide (CO), Flammable Gas leakage detector, Portable Carbon Monoxide (CO), Flammable Gas detector
