LoRaWAN hydrogen fluoride (HF) sensor is an IoT wireless device developed based on LoRa technology, integrating a high-sensitivity HF sensor and precision temperature and humidity sensor. It uses electrochemical principles for real-time monitoring of HF concentration, temperature and humidity, solving the drawbacks of traditional wired sensors (high installation cost, limited deployment, difficult maintenance) and serving as a core tool for modern HF safety monitoring.
Core Technical Advantages
The sensor’s excellent performance relies on optimized design, with three key advantages:
1. High Detection Accuracy
Equipped with a dedicated electrochemical HF probe, it avoids interference from other gases. With high-precision data calibration, the HF measurement error is within ±2% FS, and the detection range is adjustable (0-10/50/100 ppm) to meet most scenario needs. Real-time temperature and humidity compensation further ensures data reliability.
2. Stable LoRaWAN Wireless Communication
Supporting LoRaWAN protocol, it features long communication distance (3-5km outdoor, 500-1000m in industrial environments), ultra-low power consumption (2-5 years of continuous work with built-in lithium battery), and strong anti-interference ability, ensuring stable data transmission without loss.
3. Integrated & Easy to Use
The integrated design combines HF, temperature and humidity detection in one device, with simple installation and maintenance. It is widely applied in environmental monitoring, industrial emission detection, chemical plants and other scenarios.
