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 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 ...

March 2, 2022 Ever wanted to measure soil moisture? Common “soil moisture meter module arduino raspberry compatible free shipping” PCBs might deceive you with their ascetic looks.

For my totally-hypothetical at this point wireless soil moisture sensor project, I've been thinking about using supercapacitors.

Soil moisture sensors are cheap and easy to interface with, to the point that combining one with an Arduino and blinking an LED when your potted plant is feeling a bit parched is a common beginners… ...

A competent Arduino implementation (SparkFun RedBoard) can get down to around 5mA from USB (if you remove the power LED) in deep sleep mode. The cheap Chinese ones do draw a lot more (20mA in deep ...
