Sensor’s network underlying the IoT system for monitoring water bodies hydrogen ions activity in real time was demonstrated. The measuring device was tested on liquids with different pH levels. The obtained measurement results were compared using a stationary pH meter OHAUS Starter 3100 UR - http://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000892342 ER -
