This project involves interfacing an Arduino Uno with the NPK 7-in-1 Soil Sensor to measure various soil parameters including moisture content, temperature, electrical conductivity, pH level, nitrogen ...

The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

Soil Moisture Sensor Pinout. The Soil moisture sensor a.k.a the soil humidity sensor, has four pins VCC, GND, Aout, Dout.These four pins can be used to get the soil moisture data from the sensor, The ...

The JXCT Soil NPK sensor is a low-cost, quick-responsive, high precision & portable Soil NPK Sensor that works with Modbus RS485. The advantage of this sensor over a traditional detection method is ...

Note: Arduino Nano board and Amphenol Humidity and Temperature sensor was purchased from digikey for this project. When we turn on the circuit, soil moisture sensor starts measuring the water level in ...

Soil is the most important medium for plant growth. The aim of this project is to develop a detection system for major nutrients of soil; Nitrogen, Phosphorus and Potassium (NPK) which consists of an ...
