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 ...

The nano sensor interface presented below is a microcontroller-based universal sensor interface with a power-saver mechanism. The idea, centered around an Arduino Nano (v3) microcontroller, was ...

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

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

I've custom built PCB shields which drop onto an Arduino R3 which allows me to plug in an ESP8266 wifi module. I plug in 6 Moisture sensors to the shield. when it fires up, it connects to my WiFi ...

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 ...
