LoRa wireless ETO/VOC sensor is an IoT wireless device specifically designed for monitoring ETO gases. Relying on LoRa spread spectrum modulation technology, this device achieves ultra long distance communication between terminals. Equipped with high-performance chlorine gas sensors and microprocessors, it has three major advantages: high detection accuracy, stable operation, and low energy consumption. Pre set upper and lower threshold values based on environmental conditions, and proactively report abnormal data. The product is widely used in industrial safety, industrial parks, environmental protection and other scenarios.

This CE-certified industrial-grade ETO gas transmitter adopts an electrochemical principle, featuring an ultra-high resolution of 0.1 ppm and a measurement range of 0-100 ppm with a 1-second data refresh rate. The device supports RS485 output and the ModBus RTU communication protocol, with a default baud rate of 9600 bit/s and a maximum communication distance of 2000 meters. It is powered by a wide DC voltage range of 5-28V and encased in a waterproof wall-mounted housing with high protection performance, suitable for harsh industrial environments with a temperature range of -20℃ to 50℃ and a humidity range of 15%-90% RH (non-condensing). Equipped with a built-in temperature and humidity sensor, it boasts excellent anti-interference capability and is applicable to scenarios such as industrial safety and environmental monitoring, providing accurate and stable data support for gas detection.
