DFRobot Gravity NH3 Sensor Calibrated I2C UART - Ammonia Gas Detection Module
The DFRobot Gravity NH3 Sensor is a calibrated electrochemical module for detecting ammonia (NH3) concentrations from 0-100 ppm. It features selectable I2C, UART, and analog voltage outputs for seamless integration with Arduino, ESP32, Raspberry Pi, and other 3.3V/5V microcontrollers.
Features
- Calibrated electrochemical sensor for ammonia (NH3) detection, 0-100 ppm range.
- Triple-output interface: I2C (32 configurable addresses), UART, and analog voltage (0-3V).
- Low power operation: 3.3-5.5V DC supply, <5mA current consumption.
- Integrated temperature compensation and programmable threshold alarm function.
- Gravity-series connector for plug-and-play compatibility with DFRobot ecosystem and sample code.
