Understanding LoRa
In this chapter, we explore the world of LoRa (short for Long Range), a key technology in IoT communication. LoRa is known for transmitting data over extensive distances with minimal power. We will explore its practical applications in areas such as agriculture, where it enables efficient management of large-scale sensor networks, and urban settings, where it assists in smart city initiatives such as street lighting control.
We will also investigate the radio frequency spectrum and understand how different frequencies are allocated for various wireless communications, allowing us to better comprehend the operational range of LoRa technology. By studying the frequency spectrum, we can identify which frequency bands are most suitable for LoRa transmissions.
Our focus then shifts to the practical aspect: building a LoRa sensory transmitter and LoRa receiver using a Raspberry Pi Pico and Pico W, respectively. We’ll start with assembling the transmitter circuit...
