Our LoRa temperature and humidity monitoring system includes the LoRa gateway and LoRa Temp & Humidity sensor, multiple sensors could work with one gateway. LoRa has strong signal for penetration and diffraction, so the distance between them can reach maximum 5km in the open air. Gateway will gather all data from sensors wirelessly and transfer to the cloud software in real time, so you can monitor the temperature and humidity of your warehouse, cold room, medical refrigerator, supermarket, etc. anytime and anywhere.
