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 ...

An Arduino is a much better choice than a Raspberry Pi for tasks that require real-time input and responses. While a Pi can ...

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

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 ...

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

Using an Arduino, a moisture sensor, an LED matrix, and a few other parts, dr.mcc's build monitors the moisture level in a pot of soil and then lets you know when the plant needs water by ...

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 ...

I can check that annually and probably be fine. Soil moisture, though, is something that requires more active control. My long term goal is to integrate the sensors and some control relays for ...
