This Arudino project reads Capacitive Soil Moisture Sensors, measures soilMoistureValue vs AirValue vs WaterValue, and then triggers a relay module to switch water pumps on/off when needed. - ...

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 ...

Abstract: The calibration process involved comparing data from capacitive sensors with soil moisture content measured continuously by the volumetric water content (VWC) method. The results showed that ...

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 ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

Posted in Arduino Hacks Tagged capacitive sensor, ESP32, Rain sensor, sensor. ... explains exactly how capacitive soil moisture sensors work simply, clearly, and concisely.

This LoRa node used off-the-shelf components consisting of an ATmega328P-based Arduino Pro Mini ... as part of a discussion around all of the problems associated with standard soil moisture sensors.

My shed is mostly done, which means I'm moving onto other projects that look a lot like landscaping. Lawns, gardens, etc. I want to be efficient in my watering, and potentially even lazy and have ...
