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 ...

Green Thread - Arduino Nano Matter Soil Moisture Sensor A professional-grade soil moisture monitoring system built on Arduino Nano Matter with Thread/Matter connectivity for Home Assistant integration ...

Virtual Plant Mood Display with Soil Moisture and Light Sensors 🌱💡 This Arduino sketch reads soil moisture and ambient light sensor data, and displays a cute animated face on a 16x2 I2C LCD screen ...

For my totally-hypothetical at this point wireless soil moisture sensor project, I've been thinking about using supercapacitors.

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.

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 ...
