MQ-7B Carbon Monoxide Sensor
The MEu-2CO gas sensor is a fuel cell type sensor. Carbon monoxide and oxygen undergo corresponding redox reactions on the working electrode and the counter electrode and release charges to form a current. The generated current is proportional to the carbon monoxide concentration and follows Faraday's law. By measuring the current can determine the concentration of carbon monoxide.
Sensor Features
Excellent repeatability and stability.
main application
Carbon monoxide detection in commercial and civil fields.
Portable carbon monoxide detector.
Fixed point carbon monoxide detector.
