Summary
In this chapter, we explored LoRa technology, an important component in IoT communication. We started by discussing LoRa’s ability to transmit data over long distances with low power use, emphasizing its importance in wireless technology. We looked at its applications in agriculture, where it improves sensory network management for crop management, and in urban settings for smart city initiatives such as street lighting control.
We then examined the technical aspects of LoRa within the radio frequency spectrum. This includes understanding how frequencies are allocated for wireless communications, which is important for identifying the right frequency bands for LoRa transmissions.
For our hands-on sections, we built a LoRa sensory transmitter and LoRa receiver using Raspberry Pi Pico and Pico W respectively. This involved constructing a transmitter with a LoRa module and temperature sensor and a LoRa receiver using a simple LED acknowledgment.
