The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

Ever wanted to measure soil moisture? Common “soil moisture meter module arduino raspberry compatible free shipping” PCBs might deceive you with their ascetic looks. Today, [Raphael (@r… ...

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 ...

The Arduino code is explained, detailing how it reads the sensor data, converts it to a moisture percentage, and potentially displays the results on the serial monitor or through other outputs like ...

Interfacing Soil Moisture Sensor with Arduino Where should soil moisture sensors be placed? Sensors should be placed at several different depths and locations in the field. Typically, sensors are ...

As such, I'd like to build myself some wireless moisture sensors for moderate scale production (consider 50 test points reasonable).

In a way, the magic of a soil moisture sensor’s functionality boils down to a simple RC circuit. But of course, in practice there is a bit more to it than that. [rbaron] explains exactly how … ...

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 sensor ...
