XD-46 MQ137 Ammonia NH3 Sensor Module Analog Level Signal Output

Features:

• With level signal output and alarm signal indicator

• With analog signal output, voltage range: 0-5V

• Effective low level output signal can be used to drive PNP transistors. And it can be connected to the OP port of micro-controller

• The analog output voltage increases with the increase of the concentration. The higher the concentration, the higher the voltage
