The Arduino Uno Flow Sensor measures the flow rate of liquids or gases passing through it. It typically uses a hall-effect sensor to detect changes in flow, making it suitable for applications such as ...

//Arduino IDE Code for taking the data readings from mutiple flow sensors and sending the sensor data to the NodeMCU through serial communication. volatile int flow_frequency2; // Measures flow sensor ...

We start our arduino flex sensor code by defining the pins for the flex sensor and LED. Next, we define some variables where we have defined all the required parameters like VCC, the value of the ...

BMP280 Pressure Sensor with Arduino UNO – Connection Diagram. Now that we completely understand how the BMP280 Sensor works we can connect all the required wires to the Arduino UNO board, and in this ...

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 ...

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 ...
