LoRaWAN formaldehyde (HCHO) sensor is an IoT wireless sensor developed based on LoRa wireless technology, with built-in formaldehyde sensor and temperature and humidity sensors. It uses electrochemical principles to monitor the concentration, temperature, and humidity of formaldehyde in the environment in real time. This system has the characteristics of high detection accuracy, stable performance, and low power consumption, and is widely used in environmental monitoring, industrial emission monitoring, chemical plants, and other fields.

ZONEWU the methane transmitter designed by our company has strong safety, fast response speed, and strong anti-interference ability. After our company's unique compensation algorithm and multi-stage standard gas calibration, it also has the characteristics of long life, high precision, high repeatability, and high stability. Suitable for real-time monitoring of methane concentration in underground pipe galleries, underground parking lots, public toilets, garages, workshops, chemical plants, greenhouse farms, and other places. The device adopts a wide voltage 10-30V DC power supply, 485 signal output, standard ModBus RTU communication protocol, ModBus address can be set, baud rate can be changed, and the communication distance is up to 2000 meters.
