Gravity NH3 Sensor I2C and UART

The Gravity NH3 Sensor (Calibrated) is a highly precise instrument for measuring the ammonia concentration in the air, which was developed specifically for industrial and environmental protection applications. Thanks to the factory calibration, this sensor provides quick and accurate detection of ammonia traces in a variety of environments. With its ability to communicate via I2C and UART, the sensor can be seamlessly integrated into existing systems. The robust design, combined with advanced electrochemistry, ensures a long lifespan and reliable performance. Whether in industrial manufacturing, agricultural operations, or in the context of environmental protection projects – the Gravity: NH3 Sensor is the ideal choice for those who need precise ammonia measurements.

Features:

• Factory calibrated for precise measurements right out of the box.
• Supports three output modes: Analog, I2C and UART.
• High stability and sensitivity thanks to the electrochemical measuring principle.
• Integrated temperature compensation for accurate measurements under various conditions.
• Long lifespan of more than two years in operation.

Examples of use:

• Monitoring air quality in industrial facilities.
• Measurement of ammonia in agricultural operations to monitor soil health.
