MQ-9 Carbon Monoxide, Flammable Gas Sensor Module
MQ-9 โมดูลตรวจจับแก็ส Carbon Monoxide (CO) และแก็สไวไฟ
ข้อมูลเพิ่มเติม MQ-9 โมดูลตรวจจับแก็ส Carbon Monoxide (CO) และแก็สไวไฟ:
- Suitable for home or factory gas leakage monitoring devices.
- Have better sensitivity to CARBON MONOXIDE, METHANE, LIQUEFIED PETROLEUM GAS.
- High quality dual-panel design, with power indicator and TTL signal output instructions.
- DO switching signal (TTL) output and AO analog signal output.
- TTL output valid signal is low. (When the output low signal is on, it can be directly connected micro-controller or relay module.)
- Analog output voltage: the higher concentration, the higher voltage.
- Four screw holes, easy positioning.
- Long life and stability, quick response and resume.
