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 ...

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 ...

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 ...

The ESP02 based system has been quite reliable. Now I need to finish hooking up moisture sensors. I'm moving to a JSON protocol - a friend is doing a web interface for the system. So I've been ...

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 ...

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 ...

Plant-related posts are growing in popularity on Gadget Master, when regularly watered with attention... so hopefully this Arduino-based system to monitor soil conditions will be of interest. It's the ...
