LoRa Technology LoRa is getting popular now days and used in IoT network protocol. LoRaWAN (Long Range Wide Area Network) has applications for long distances and is designed to provide low-power for communication in IoT, M2M applications. It has a capacity of connecting millions of devices with data rates ranging from 0.3 kbps to 50 kbps. The distance for LoRaWAN application ranges from 2 – 5km for the urban environment & maximum 15km for the suburban environment. Products like MS8607, HTU21D, and MS5637 which are used to get humidity, temperature & barometric pressure values using the LoRaWAN protocol and has a major role in the field of IOT.
