If you are designing your own intelligent “Graden Computer” with an optional digital plant moisture sensor/water pump controller ... to one analog input (A0) of the Arduino. Here is the test code that ...

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 ...

This sensor is relatively complex to set up, but it works with older Arduino boards like the first-gen Uno. Measuring the pH level of a water source can give you a range of information about the ...

In this project I’ll introduce a new type of analog sensor that detects moisture levels ... black wire to GND and its red wire to Arduino pin 11. 5. Check that your setup matches that below, and then ...

ESP32 boards may be complex for beginners but offer a wide range of features ... download the specific code library for your ...

So, Instructables user dr.mcc built a moisture sensor that alerts you when you need to water a plant by using an emoticon. Using an Arduino, a moisture sensor, an LED matrix, and a few other parts ...
