As shown below pH sensor output is connected with analog read input of the arduino board. The pH sensor provides different analog outputs for different liquid solutions. By knowing pH value of known solution such as water one can easily determine pH value for other liquid solutions. The pH met...
Now, let usinterface the Soil Ph Sensor with the ArduinoNano Board using theMAX485 Modbus Module. The connection diagram is given below. TheR0 & DIpin of from the Modbus is connected toD2 & D3of Arduino using Software Serial. Similarly, we have to enableDE & REhigh which is done by co...

In a practical setting, on one side of the sensor, the reference electrode is exposed to a well-known and constant solution of hydrogen-ion activity, e.g., a buffer solution. On the other side of the sensor, the electrode is in contact with the pH solution under study. Due to the af...
Project 4.pH Sensor: Assembling, Coding, & Calibrating with Arduino | Smart Gardening Introduction:This video talks about what pH sensors are, why use them for aquaponics system, and how to assemble, code, and calibrate the Gravity: Analog pH Sensor (Version 2). ...
It’s the sensor package where this build really shines, however. There’s the usual accoutrement of temperature and humidity sensors, and a soil moisture probe, as we’d expect. But there’s more, including an impressive soil pH tester. This involves a robotic arm with a scoop to collect...
