Like many Arduino sensors, soil moisture detectors only have three pins: GND, VIN, and data. This means that they only take up a single data pin on your Arduino board. Counting your own pulse is a ...

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 ...

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 ...

An Arduino is a microcontroller ... All it requires is a moisture sensor, a water pump, and some sort of container to hold a ...

Soil moisture sensors are cheap and easy to interface with, to the point that combining one with an Arduino and blinking ... The custom board can read from six soil sensors. In his extremely ...

The board is simple because the operation of the device is simple. A fixed resistor creates a voltage divider with the soil, and dry soil has higher resistance than moist soil. A pot sets a ...

Thankfully, the Arduino board is one of the most popular electronics ... ranging from simple tutorials — like using a soil moisture sensor with Arduino — to more complete guides like building ...

so hopefully this Arduino-based system to monitor soil conditions will be of interest. It's the Squirrel Box, from researchers at the Universities of Newcastle and Nottingham. What is a Squirrel Box?
