LoRaWAN Wireless Methane CH4 Concentration monitoring sensor detector transmitter for indoor high-precision air quality monitor
LoRaWAN Methane CH4 Concentration monitoring device, Calibration also features long life, high precision, high repeatability and high stability. Applicable to underground pipe corridors, underground parking lots, public toilets, garages, workshops, chemical plants, greenhouse farms, etc. where real-time monitoring of methane concentration is required.
Based on advanced Lora spread spectrum technology, a long-range contact tracker for Class A type devices based on the LoRaWAN open protocol and is compatible with the LoRaWAN protocol. with high accuracy, good consistency, and calibration-free. no wiring required, easy construction.
Optional: LCD screen to display sensor data / 1 relay alarm output,
For Power supply, can also offer Battery Power supply
For parameters: also can integrates illumination, CO2, O2 etc sensors in one shell.
* LoRaWAN features
1.Transmission distance: Outdoors in open air> 2000 meters (external antenna, 20dBm, SF10); the longest distance is up to 6KM, (external antenna, 20dBm, SF12).
2.Working frequency: ISM frequency band including 433, 868, 915 MHZ, etc.
3.Modulation method: based on spread spectrum technology, a variant of linear modulation spread spectrum (CSS), with forward error correction (FEC) capability, proprietary patented technology of semtech
4.Transmission rate: hundreds to tens of Kbps, the lower the rate, the longer the transmission distance.
