LoRa NH3 Sensor: A New Choice for Intelligent Environmental Monitoring

With the rapid development of internet of Things (IoT) technology, remote environment monitoring has become an important demand in fields such as industry, agriculture, and urban management. Ammonia (NH₃) as a common harmful gas, the concentration monitoring in places such as farms, chemical plants, and garbage disposal stations is of great importance. The LoRa  NH₃ sensor combines advanced ammonia detection technology and long-distance low-power communication capabilities, providing an efficient solution for environmental monitoring.

How the LoRa NH₃ Sensor Works

Ammonia Gas Detection Technology

Modern LoRa NH₃ sensors usually use one of the following detection techniques:

• Electrochemical Sensor: generates an electrical signal through a chemical reaction between ammonia and the electrode 
• Semiconductor sensor: using the sensitivity of metal oxide semiconductor materials to ammonia gas
• Optical sensor: based on the principle that specific wavelength light is absorbed by ammonia gas

LoRa Communication Technology

LoRa (Long Range) is a low-power wide-area network (LPWAN) technology with the following characteristics:

• Long communication distance (2-5 km in urban environment, up to 15 km in suburban areas)
• Extremely low power consumption (battery life up to several years)
• Strong penetration ability (suitable for complex environments)
• High-capacity network (single gateway can connect thousands of nodes)   

The Core Advantages of  The LoRa NH₃ Sensor

1.Remote monitoring  capability: No need for wiring, can be deployed in a wide area

2.Low power consumption design: Suitable for long-term monitoring in places without power supply

3.Real-time data feedback: Real-time data upload through LoRaWAN network
