The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

The code reads data from a soil moisture sensor connected to analog pin A0 and calculates the soil moisture percentage. #define SENSOR_PIN A0 : This line defines a preprocessor macro, assigning the ...

For now, just moisture. However, there's no reason I can't add more sensors if I want to. pH isn't something that's going to be changing rapidly. I can check that annually and probably be fine.

The threshold moisture level is user-calibrated depending on the plant type. Bluetooth Module Uses serial communication to transfer data between the Arduino and Smartphone. Software & Bluetooth ...
