This arduino moisture sensor module is designed in a way that it can output data in both digital and analog modes. We will read this data and display the output status with an LED for digital output ...

The GP2Y1014AU0F Dust Sensor module has 6 pins; those are V-LED, LED-GND ... we can connect all the required wires to Arduino and then write our code to get the data out of the sensor module. The ...

OFF: Water detected. Open the Serial Monitor in the Arduino IDE (set to 9600 baud) to view the water detection status and sensor readings. Threshold Value: Adjust THRESHOLD to match the sensor's ...

Using a 5V RS485 soil NPK sensor, a Max485 RS485 converter module, and a 20x4 LCD display, the system-which is based on the Arduino Nano platform-monitor nitrogen, phosphorus, and potassium levels in ...

Phosphorus and Potassium (NPK) which consists of an optical sensor. The optical sensor is developed with two systems which are transmission system and detection system. The transmission system uses ...
