AbstractThis paper gives information for measuring the pH value by IoT based Digital pH meter using Arduino. This paper also focuses on the schematic circuit design for its digital display system. The system is a variable device that is easily adapted to a wide range of measurements. The user can measure the pH value of any liquid solution and semi-solid. A glass bulb type electrode located at the tip of the probe has been used. The pH value is dependent on the temperature of the solution therefore temperature variations are also noted through a sensor and the corresponding pH readings have been displayed on Liquid Crystal Display. The readings can be shared and transferred through IoT. ESP2866 Wi-Fi module has been used to store the pH readings on ThingSpeak cloud for processing and analyzing the data.Keywords: pH, Arduino, ESP2866, IoT, Liquid Crystal DisplayCite this ArticleHimani Garg, Praveen Kumar, Preeti, Ameesha Singh, Himanshu Maheshwari.
