Development of remote monitoring for solar heating systems

This article presents a novel method for developing a stationary remote monitoring system for solar heating / hot water supply systems designed for industrial or residential use. The system is based on a T-Call ESP 32 SIM800L board with a BME280 sensor that can operate in deep sleep mode. The logic board contains a SIM card to connect to the Internet on a data plan. It communicates sensor readings to the server and goes back to sleep mode. The presented case has 60 minutes of sleep, which can be reconfigured easily in the code. The proposed system of remote monitoring and control enables more efficient utilization of solar collector systems for industrial and residential heating and hot water supply.
