The DFRobot Gravity: NH3 Sensor (Calibrated) - I2C & UART is an electrochemical gas sensor module for ammonia (NH3) detection with analog, I2C, and UART outputs. The probe is factory calibrated and supports 32 changeable I2C addresses, temperature compensation, and threshold alarm functionality. More product details

Product Description

The DFRobot Gravity: NH3 Sensor (Calibrated) - I2C & UART is an electrochemical gas sensor module for measuring ammonia concentration in ambient environments. It combines a factory-calibrated NH3 probe with a signal conversion board and provides measurement data through analog, I2C, or UART output. This makes the module suitable for integration into embedded systems and instrumentation with different interface requirements.

The probe uses the electrochemical sensing principle and is designed for stable and sensitive NH3 detection. According to the manufacturer, the module includes an integrated temperature compensation algorithm, a threshold alarm function, and 32 modifiable I2C addresses. The Gravity interface simplifies connection to common control and development platforms such as Arduino, ESP32, and Raspberry Pi.

Technical Features

Electrochemical gas sensor module for ammonia (NH3) detection
Factory-calibrated probe for faster deployment
Output interfaces: analog, I2C, and UART
32 modifiable I2C addresses for multi-device operation
Integrated temperature compensation algorithm
Threshold alarm function for application-specific monitoring
