MQ-7 Carbon Monoxide Detection Sensor Module CO Gas Sensor Module MQ-7 Gas Sensor Module Carbon Monoxide Detection Sensor Module MQ-7 Gas Sensor Module Carbon Monoxide Detection Sensor Module Co Detection Description: 1. Dimension: 32mm X 22mm X 27mm 2. The main chip: LM393, MQ-7 gas sensors 3. The working voltage: DC 5 V 4. Characteristics: 1>having a signal output instruction. 2>dual signal output (analog output, and TTL level output) 3>TTL output valid signal is low. (Low-level signal when the output light can be directly connected to the microcontroller) 4>0 ~ 5V analog output voltage, the higher the concentration the higher the voltage. 5>carbon monoxide has a high sensitivity and good selectivity. 6>has a long life and reliable stability 5. Application: Carbon monoxide detection sensor to protect family environment. Suitable for the detection of carbon monoxide, gas, etc.
