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.

I'm planning to have a "spider" of moisture sensors off one Arduino - 5 or 6 coming off one box.

Implementation of LoRaWAN-based soil moisture sensing device. (Credit: Maja Škiljo et al., 2022) Although we generally think of Internet of Things (IoT) and similar devices as things that are ...

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 ...
