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 ...

First, we’ll build a simple soil moisture monitor with Arduino, according to this schematics. Here’s what you need: Arduino board Breadboard Jumper wires Resistance-based soil moisture sensor Three ...

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.

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...

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 ...

An Arduino Nano reads in from the soil moisture sensor, and if the soil is dry, the plant screams. If the soil is moist, the plant emits happy sounds from DF Player Mini and SD card.

The calibration process involved comparing data from capacitive sensors with soil moisture content measured continuously by the volumetric water content (VWC) method. The results showed that sensor ...

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.
