In this article, we present a pH meter that can accurately measure the pH value of a solution. We use a dedicated sensor, the Arduino UNO R4 Minima board.

Arduino Water Level Sensor Circuit – Connection Diagram Now that we completely understand how the water level sensor works, we can connect all the required wires to the Arduino UNO board, and in this ...

Interfacing the Rain Sensor with Arduino Now that we completely understand how the Rain Detection Sensor works, we can connect all the required wires to the Arduino UNO board. This section of the ...

Ensure the DHT11 sensor is correctly connected to the Arduino Uno and powered. The DHT sensor library simplifies communication with the sensor and provides reliable humidity readings.

As you can see in the photo above, the Arduino headers are exposed as well as the 6-pin ICSP header in order to connect it to the Arduino UNO board. If the ten sensors included in the kit are not ...

The pH meter project features open software and open hardware design circuit which can be connected with an electrode pH sensor made of glass. The device is termed as pHduino which can operate by ...

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 ...
