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 ...

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) ...

In this study, an Arduino-based wireless sensor network system was developed and tested to monitor volumetric soil water content using Decagon EC-5 sensors. The system uses a start topology in which a ...

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 ...

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...

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.
