Ultrasonic Sensor Module. There are many types of Arduino distance sensors, but in this project we have used the HC-SR04 to measure distance in range of 2cm-400cm with an accuracy of 3mm.The sensor ...

BMP180-PressureMeasurement: Demonstrates how to measure pressure, altitude, and temperature using the BMP180 sensor module with Arduino. HCSR04-DistanceMeasurement: Demonstrates how to measure ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

Logic behind Measuring Speed with LM393 speed sensor module. From the sensor mounting set-up you should be aware that the LM393 speed sensor module (H206) measures only the gaps present in the grid ...

I made this library to make it easier for others to get up and running with this module. What this module does is very simple. It reports a 1 bit signal based on the distance of an object from it. It ...

Code uploadWe can now load our Arduino sketch to the RAK4631 development board.Selected the board in the Arduino IDE, as well as the correct port, and start the code uploading and flashing. You may ...

Proximity Sensor Switch – Circuit Diagram. The circuit diagram of the wireless load control unit is shown in Fig. 2. This design is based on Arduino Nano board and built around an I2C LCD (module1).
