Description
MQ-7 CO Carbon Monoxide Coal Gas Sensor Module
| Detection Range | 10 to 1000 ppm |
| Characteristic gas | 100 ppm CO |
| Sensitivity | ≥ 3%. |
| Ambient temperature (°C) | -20 to + 50 |
| Operating voltage (v) | 5 V |
The MQ7 CO Carbon Monoxide Coal Gas Sensor detects the concentrations of CO in the air and outputs its reading as an analog voltage. The sensor measures concentrations of CO from 10 to 10,000 ppm.
The threshold level for digital output can be easily adjusted using the preset on the board. The MQ7 sensor module can be easily interfaced with Micro-controllers, Arduino and etc.
