Abstract:
Sensors are quite important for agricultural risk monitoring, and the customization of a LoRa wireless network and its use in rural applications is still a challenge. This paper presents a data collector system based on a Wi-Fi and Lora platform. The arrangement includes an ESP32, which is a single 2.4 GHz Wi-Fi and Bluetooth combo chip designed to operate with ultra-low-power and based on the 40 nm technologies. Therefore, the module allows using both protocols for Wi-Fi and LoRa wireless networks. One of the main characteristics, which was leveraged in this study, is its applicability for longrange communication in rural areas with low power consumption. During operation, the proposed receiver node is connected to the internet, thereby enabling data storage on servers, such as ThingSpeak, which is an Internet-of-Things analytics platform service. The results in a controlled-environment test showed that the connection between the station and receiver was fully functional at a distance of 500 meters. Besides, once this advanced data collector, currently under development, is finished, interconnection of several stations will be possible, even if they are remotely located with respect to the receiver node.
