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 ...

Using an Arduino, a moisture sensor, an LED matrix, and a few other parts, dr.mcc's build monitors the moisture level in a pot of soil and then lets you know when the plant needs water by ...

The calibration process involved comparing data from capacitive sensors with soil moisture content measured continuously by the volumetric water content (VWC) method. The results showed that sensor ...

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 ...

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 ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...
