Sometimes, a project comes along that makes a good reference design for anyone doing similar work. In this particular case, it’s a DIY USB polygraph-like machine by [Juangg] using an Arduino … ...

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 ...

If your Arduino soil moisture sensor isn't working, check these common issues: verify all wire connections are secure, ensure you're using the correct Arduino pins (A0 for analog, digital pin for ...

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 ...

Soil Moisture Monitoring with Arduino – Circuit Diagram. Fig. 3 shows the physical connection of the system, while Fig. 4 provides the schematic. In both diagrams, the sensor’s output signal pin is ...

This is my first time writing a library for Arduino or anything, so all feedback is most welcome. If anybody has any questions or comments, please let me know. Thanks. SoilMoisture::readSoil() Takes 5 ...

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

My shed is mostly done, which means I'm moving onto other projects that look a lot like landscaping. Lawns, gardens, etc. I want to be efficient in my watering, and potentially even lazy and have ...

A low cost Arduino based Automatic Irrigation system using Soil moisture sensor is presented in this paper in which the soil moisture sensor gives it's output depending on the conditions of the soil ...
