Water Level Monitoring System Based on LoPy4 Microcontroller with LoRa technology

Abstract:

Modern weather stations allow real-time monitoring of several atmospheric variables. Wireless Sensor Networks (WSN) provide communication between nodes and the Network Coordinator (Gateway). This network uses transceivers to send the data generated by the stations. The use of WSN in remote locations involves the construction of repeaters because there is no cellular signal or an access network. This article presents the development of a datalogger for stations that measure river water levels of the andean region. The LoPy4 microcontroller is used. This solution combines easy sensor configuration via WiFi and long-range transceiver with LoRa (Long Range) technology. The proposed datalogger has a solar power supply and allows real-time data transmission using the SX1272 transceivers, while a GPRS module is integrated in the coordinator for transmission to the monitoring station server. A GPRS module is integrated into the gateway to forward the data from the stations to the data center.
