The Arduino and soil sensor communication is established using the RS485 communication protocol. Connect the Arduino Uno to the RS485 module according to the circuit diagram. Connect the RS485 module ...

If you are designing your own intelligent “Graden Computer” with an optional digital plant moisture sensor/water pump controller that lights an LED to alert the user when it is time to water a potted ...

As shown in the above arduino soil moisture sensor circuit diagram we have connected an LED to digital PIN 6 of the Arduino and the analog out pin of the sensor is connected to the A0 pin of the ...

The sensor helps detecting the NPK values along with soil-moisture, soil-humidity, soil-pH and soil-temperature. The testing of this sensor is achieved with the help of Arduino UNO. The code written ...

I have connected the moisture sensor to Arduino, to get the information about the soil. Then I have connected a resistor in series to the motor pump as a load, since I have used USB as power input to ...

Abstract: Soil is the ... 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 ...
