Intelligent Infrared CO2 Module (Model: MHZ19B)

Do not use the sensor in the high dusty environment for long time. To ensure the normal work, the power supply must be among ~ DC rang, the power current must be not less than 150mA. Out of this range, it will result in the failure of the sensor. (The concentration output is low, or the sensor can not work normally.)
