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 ...

Set up a simple circuit to turn the Arduino on when the battery voltage goes above a threshold (Those old BEAM SolarEngine circuits should work with small modifications) and then just have 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 ...

The soil sensor switches half of an etched PCB bowtie antenna in and out of a circuit at a frequency proportional to soil moisture.

I found instructions for several Arduino-based plant sensors online, including the GardenBot, the ArduGarden, and a solar-powered sensor that measures soil fertility and weather conditions.

An Arduino is a much better choice than a Raspberry Pi for tasks that require real-time input and responses. While a Pi can ...

I think the power use of waking the Arduino every 8s after 90% of the sleep time will probably be less than the power use of leaving the wireless radio connected for 5-6 minutes, and I'd like my ...
