This paper discusses the possibility of creating a digital platform based on Mojo v3 for monitoring the operation of a dual-circuit solar collector. In the proposed system, measurements are made from 6 digital sensors, 16 wires are used. Using Dallas sensors and the appropriate software, you can monitor the temperature level and the amount of heat. The use of 6 digital sensors significantly increases the efficiency of control over the system and increases the speed of data processing. The possibilities of (...) configuring sensors for the platform Mojo v3, as well as the control circuit of the solar collector are considered. (shrink)
