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 ...

Always under-watering or over-watering your plants? Wire up this Arduino-based sensor and save them.

The system here monitors temperature, humidity, and smoke levels and alerts you if those levels reach a certain point.

I'm planning to have a "spider" of moisture sensors off one Arduino - 5 or 6 coming off one box. Again, I doubt you need continuous monitoring even with multiple sensors.

Soil moisture is critical for climate systems, hydrology and agriculture. While passive microwave remote sensing is effective for large-scale soil moisture monitoring, it often has low spatial ...
