Among them were, measuring soil N, P, K using a portable device consisting Arduino UNO and an LED (Masrie et al., 2018), which laid foundation to develop portable optical NPK sensors based on VNIR spectroscopy, developing colorimetry based sensing systems (Liu et al., 2016) and analyzing ...
The optical sensor is developed with two systems which are transmission system and detection system. The transmission system uses LED powered by Arduino UNO as a component to transmit light directly on the soil which contains nutrients in a transparent container. The detection system utilized two ...
The main aim of this proof of concept model is to construct a soil nutrient testing kit using Arduino UNO board and sensor module. This project gives the details regarding the amount of macro-nutrients and micro-nutrients present in the given sample of soil. The pH value and electrical ...
By using an Arduino Nano microcontroller as a control system equipped with sensors to measure and monitor soil environmental conditions. The sensors are NPK, soil moisture sensor, temperature sensor, and pH sensor that complement the Arduino Nano microcontroller. Utilizing the lower and upper limit ...
The device building included market surveys and opted for an inexpensive, light, and compact soil sensor, power storage, monitor, and wire connectors. Arduino programming language was used to write scripts for data display and sub-device communication. The result is a real-time, portable soil ...
Arduino, respectively. The NPK sensor features four wires: the red wire (VCC), requiring a 5V–24V power supply, which should be connected to the VCC on the Arduino; the black wire (GND), which should be connected to the Arduino’s GND; the blue wire (B pin), which should be ...
Figure 3.Soil sensor’s architecture. We used two types of microcontrollers in this work: Arduino Nano and Arduino Nano 33 IoT with technical parameters as presented inTable 2. Arduino Nano 33 IoT is the smallest board that can be used with Internet of Things (IoT). It contains a Cortex...
The studies have revealed that the Agrinex NPK soil testing tablets should be applied to a soil sample, and then the soil colour can be sensed using an LDR colour sensor to predict the phosphorus (P), nitrogen (N), and potassium (K) values. These collected data together were stored in ...
