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 ...

It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot form a variable resistor, whose resistance varies depending on soil moisture. This variable resistor is connected in ...

This Arduino Project Hub guide shows you how to set up an AMG8833 thermal camera with an OLED display for an Arduino.This sensor is relatively complex to set up, but it works with older Arduino ...

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.

As a preview of his latest book, Arduino Project Handbook: 25 Practical Projects to Get You Started, Mark Geddes takes us through the project to create a simple plant monitor. In this project I’ll ...

ESP32 boards may be complex for beginners but offer a wide range of features for DIY projects. Projects like a Wi-Fi scanner, web server, weather station, and smart soil monitor are great for ...
