SGHG01 เซนเซอร์ก๊าซ ไฮโดรเจน Gas Sensors Hydrogen (H) MQ-8
Technical Parameter
- ตรวจจับแก๊ส ไฮโดรเจน Hydrogen (H) Gas
- ตรวจจับความเข้มข้น Detection Range
- Input voltage: DC5V
- DO signal (TTL) output (0.1 and 5V)
- AO analog signal output 0.1-0.3V (relatively pollution-free), the highest concentration voltage is about 4
- Power consumption (current): 150mA
- After the sensor is powered on, it needs to preheat for about 20 seconds before the measured data is stable.
- It is normal for the sensor to heat up, because there is a heating wire inside, if it is hot, it will be abnormal.
- Dimensions: 32(L)*20(W)*22(H)
- The gas sensitive material used in the MQ-8 gas sensor is tin dioxide (SnO2) with low conductivity in clean air.
- When there is combustible gas in the environment where the sensor is located, the conductivity of the sensor increases with the concentration of combustible gas in the air.
- The change in conductivity can be converted into an output signal corresponding to the gas concentration using a simple circuit.
- The MQ-8 gas sensor has high sensitivity to hydrogen and is ideal for monitoring other hydrogen-containing gases.
- This sensor can detect a variety of hydrogen-containing gases, especially city gas, and is a low-cost sensor suitable for many applications.
Application:
- Domestic Hydrogen (H) Gas concentration detector, Industrial Hydrogen (H) Gas leakage detector, Portable Hydrogen (H) Gas detector
