Abstract

Refrigeration installation there is usually a cooling unit (heat exchanger) and a cooling tower. overall cooling is warm water coming from the heat exchanger is flowed to the cooling tower to launch heat into the air. While the release of heat is carried out, of course followed by continuous evaporation of water so that the volume of water for cooling becomes less so that the quality of the water in the cooling tower needs to be maintained where if the concentration has exceeded the saturation limit it will cause problems in other cooling units. Water quality measurement uses the TDS sensor and the control controller system uses Arduino Uno while the monitoring system uses the Wemos D1R1 controller where the measurement results are sent to the ThingSpeak web as data storage that can be accessed via the online. The TDS sensor test results from 20 trials have an accuracy level 96.80% of the results of testing the controller accuracy system have a success rate of 100% and the results of the internet of things (iot) test show that the value of sending sensor data at intervals of 15 seconds and delaying delivery to ThingSpeak for 5 seconds so that sensor data can be said to be realtime.
