The pH sensor is inspired from phDuino. It is composed by an amplifier and a 2nd order low-pass filter (Rauch) The amplifier is designed to span the input range of a typical pH probe (-400 -> 400 mV) ...

Our objective in this study was, therefore, to develop and test an affordable wireless communication system for monitoring soil moisture using Decagon EC-5 sensors. The new system uses ...

Using an Arduino NANO or just about any Arduino you can create a very accurate PH & EC/TDS meter for hydroponic and gardening. Connect your Arduino to your computer, start the Arduino IDE and flash ...

We connected $\\mathbf{p H}$ sensor and solar cell into Arduino Board to control data transmission via red laser communication or popular known as visible light communication (VLC). The sensor was ...

Because of the affordability and seeming ubiquity of the Arduino platform, they have been hard at work this last month trying to get their Geiger counter sensor board for an Arduino out the door.
