MQ-137 Ammonia Detection Sensor NH3 Gas Sensor Module 

Detailed Description:

  • Main chip: LM393, NH3 gas sensor probe
  • Working voltage: DC 5V
  • Module size: 35 x 30 x 22mm
  • Application: for harmful gas detection device used in home and environment, suitable for ammonia vapor detection

Sensitive gas: Ammonia Detection Sensor NH3 Gas 

Feature:

  • With signal output indicator light
  • Dual signal output (analog output and TTL level output)
  • TTL output effective signal is low level; (the signal light is on when the output is low level and can be connected to the MCU IO port)
  • The analog output increases as the concentration increases, the higher the concentration, the higher the voltage
  • It has high sensitivity and selectivity to ammonia.
  • It has a long service life and reliable stability.
  • Fast response and recovery characteristics.
  • With mounting holes, convenient for fixed installation.
  • The probe can be plugged and unplugged to facilitate testing.
