MQ-7 MQ7 CARBON MONOXIDE KARBON MONOKSIDA CO GAS DETEKTOR SENSOR

MQ-7 MQ7 CARBON MONOXIDE KARBON MONOKSIDA CO GAS DETEKTOR SENSOR
DESCRIPTION
This is very simple to use, suitable for sensing CO concentrations in the air. The MQ-7 can detect CO-gas concentrations anywhere from 20 to 2000ppm.

This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.

Rated Voltage: DC 5V
Rated Current: 180mA
Mainly used for CO collection detection in family, factory, underground operation.
