Today, we are going to make the most practical iOT based Hydroponic System using the ESP32 WiFi + Bluetooth Module, the DFrobot’s Gravity Analog pH Sensor Kit V2, EC or TDS Sensor, Analog Signal Isolators, DS18B20 waterproofed one-wire digital temperature sensor, the most versatile UART version of the A02YYUW Waterproof Ultrasonic Sensor, and Blynk application for the monitoring.
Let’s first start with the Gravity Analog pH Sensor kit V2. And let me also tell you this is the upgraded version of the pH meter V1 which could only be used with 5V compatible controller boards, whereas the pH Meter V2 is compatible with both 3.3V and 5V compatible controller boards.
Inside this box you get a product qualification card.
A paper that gives you an introduction, technical details, and safety tips about pH sensor.
A pH probe with the BNC connector.
The pH sensor interface board or the signal conversion board. It must be kept dry and clean, otherwise, it will affect the input impedance, resulting in an inaccurate measurement.
Some wires and screws.
And standard buffer solutions 4.0 and 7.0. For the perfect calibration of the pH Sensor, you should have these buffer solutions. That’s why I ordered this complete kit.
I also ordered two Analog Signal Isolators. If you have ever used a pH sensor and an EC sensor at the same time in the same container, you know that the sensor readings can get messed up because of ground looping. So, to avoid ground looping, I am going to use two Analog Signal Isolators. I will use one with the pH sensor and the other one with the EC sensor.
