Bluetooth Home Automation With CloudX

Bluetooth wireless technology has grown to become one of the widely used protocols in the field of communication today. Although it has lower range of reach when compared to other wireless communication protocols such as WiFi and ZigBee ─with which it operates on the same frequency of 2.41 GHz; it is still very suitable for many low range applications. As a matter of fact, it has an enough bandwidth to meet most of our regular mobile and personal communication demands. It [...]

Interfacing Moisture Sensor with Arduino

Interfacing Soil Moisture Sensor with Arduino

Introduction In this article, we are going to interface a Soil Moisture Sensor with Arduino Uno. We will measure the moisture content of soil in pot or farming field and by using this we can pour water into field based on preset values. This sensor measures the volumetric content of water inside the soil (based on resistance/conductivity) and gives the moisture level as output. The sensor is equipped with both analog and digital output, so it can be used in both [...]
