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
4.Multi-parameter monitoring: High-end models can simultaneously monitor environmental parameters such as temperature and humidity.
5.Easy to deploy: Plug and play, quick network setup
