The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

When I started working on my soil moisture sensor, I had little idea about how harsh an environment the soil really is. In this 🧵, cool failure modes & solutions when sticking electronics in ...

My soil-moisture reading was in the low 700s in soil that had around 30 percent moisture (according to a comparison with a commercial soil-moisture sensor), and 661 in a drier pot.

Using an Arduino shield extension board together with a NB-IoT BLE Gateway and BLE Sensor Probe the open source system allows you to connect to 25 ...

Use an Arduino board to build a computer to run your whole garden. Kind of like HAL from 2001, except (knock on wood) it won’t try to kill you. Know exactly how hot and how cold your plants 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… ...
