Carbon Monoxide Sensor - MQ-7 (SEN-09403)
£3.68 ex VAT
This is a simple-to-use Carbon Monoxide (CO) sensor, suitable for sensing CO concentrations in the air. The MQ-7 can detect CO-gas concentrations anywhere from 20 to 2000ppm.
This sensor has high sensitivity and a fast response time. The sensor's output is analogue 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.
This sensor comes in a package similar to our MQ-3 alcohol sensor and can be used in our other gas sensor boards.
