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 ...

I'd probably use one module to run 5 or 6 sensors, conformal coated and buried. I'll do some shallow trenching for wires, and mark the sensor locations somehow so I don't mow over them.

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 ...

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… ...

Soil moisture sensors can help farmers save water, by letting them know when their crops actually need to be watered. A new sensor could be particularly helpful, as it incorporates a special ...

For now, just moisture. However, there's no reason I can't add more sensors if I want to. pH isn't something that's going to be changing rapidly. I can check that annually and probably be fine.
