Module with an analog MQ7 carbon monoxide sensor. Carbon monoxide (most often called carbon monoxide) is a gas that is colorless, odorless, tasteless and extremely poisonous. Due to these properties, carbon monoxide is difficult to detect without a specialized device. With the help of the module with the MQ7 sensor, it is possible to build a detector that will detect CO in our environment. The module is powered with 5 V and has an analog output (Gravity connector) proportional to the measured concentration. The sensor is characterized by high sensitivity adjustable with a potentiometer and can measure the concentration of CO in the range from 20 to 2000 ppm. The Wiki page contains the manual and sample programs.
