Simply connect the moisture sensor and the water pump (through the relay) to the Nano RP2040 Connect board, insert the moisture sensor in a flower pot, and put the pump in a recipient filled with ...

Resistance-based soil moisture sensor; Three LEDs (red, yellow, green) Three 220 ohm resistors; Glass of water; Connect the 5V and GND ports of the Arduino to the breadboard. Attach the sensor power ...

Basically we have the Arduino Uno R4 which will read the soil moisture level using the soil moisture sensor. If the moisture is low it will automatically turn on the water pump via the relay module.

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 ...

Capacitive soil moisture sensors exploit the dielectric contrast between water and soil, where dry soils have a relative permittivity between 2-6 and water has a value of roughly 80. Accurate ...

Before you start working with moisture sensors, consider the following tips about sensor selection and sensor integration. Once you are familiar with the bascs, you can begin integrating the sensors ...
