Product Introduction
The ammonia gas sensor module MMD1002 is developed using a MEMS micro gas sensor, which can be used to detect the NH3 gas level in the air. The module has a high sensitivity to NH3 gas. The module has been aged, debugged, calibrated in factory, and has good consistency and long-term stability.
Main Application
Fixed and portable testing instruments, smart refrigerators, restroom monitoring, agricultural animal husbandry environment monitoring and other places.
Sensor Module Characteristics
High sensitivity
High resolution
Low power consumption
Long life time
Provides multiple output method such as UART, analog voltage, PWM, etc
High stability
Excellent linear output
