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 ...

If your Arduino soil moisture sensor isn't working, check these common issues: verify all wire connections are secure, ensure you're using the correct Arduino pins (A0 for analog, digital pin for ...

Fig. 2: Circuit diagram of the digital soil moisture meter. Front-end of the digital soil moisture meter is a simple soil moisture sensor head, built around a few easily-available parts. Working of ...

It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot form a variable resistor, whose resistance varies depending on soil moisture. This variable resistor is connected in ...

This library (with examples) is designed to be integrated in projects using any kind of Hygrometer sensors like rain drop or soil moisture sensors (analog or/and digital). It retrieves analog/digital ...
