In this tutorial, we will design our own DIY IoT Based Water pH Meter using a pH Sensor & ESP32 WiFi Module. In some earlier tutorials, we interfaced pH Sensor with Arduino to make a portable ph Meter. The pH reading data was displayed on OLED Screen.
This is a completely different tutorial as we will be using a better and advanced pH Sensor. The pH Sensor used here is an analog type pH Sensor that gives a linear pH reading in 0pH to 14pH range. Instead of displaying the data on an OLED screen, we will send the data to ThingSpeak Server. The ThingSpeak provides instant visualizations of data posted by our device, i.e. ESP32. Since ESP32 is a 12-bit controller with built-in ADC, so it can measure data more precisely compared to Arduino which has a 10-bit ADC.
It incorporates a high-resolution pH probe that samples liquid pH at user-defined intervals and transmits the result to remote servers. The pH probe comes with a 5 long cable and can be dipped in any solution. The response time is lesser than a minute. We can incorporate this IoT Based pH Meter in Aquariums, Hydroponics, laboratories, etc. So let us learn how we can interface pH Sensor with ESP32 & make our own pH meter. The tutorial also covers the pH Sensor Calibration method.
