ZONEWU Based on LoRa spread spectrum modulation technology, terminals are capable of ultra long distance communication. A wireless monitoring device that integrates data collection, monitoring, and transmission. This product is equipped with a methane (CH4) sensor and a temperature and humidity sensor. The use of non dispersive infrared (NDIR) principle for detecting methane gas in the air has good selectivity and is oxygen independent. This sensor is equipped with emergency reporting of data anomalies, and can proactively report anomalies based on pre-set threshold values according to the on-site environment. It supports standard LoRaWAN protocol and TDMA networking protocol for ad hoc networks.
