Abstract
The idea of research is based on long distance low power wireless communication. The primary objective is to prolong the battery life of the communication device connected to the sensors. This is done by providing single gateway to multiple nodes. Conventionally in IoT (Internet of Things) applications, the sensors are interfaced with 3G/4G modules to push the data to the server directly. Hence, individual devices require more power to send data to the server. This would deteriorate the battery backup of the system and would increase the power dissipation. By using LORA node-gateway network, a group of sensors send data to a single gateway which requires less power compared to the conventional methods. This article provides insight about the LoRa sensor node design and enclosure setup. Chirp Spread Spectrum (CSS) or Frequency Shift Keying (FSK) modulation technique is used to encode the data that is to be sent to the server under this scheme. The data acquired at the gateway is formatted and forwarded to the server.
