Arduino and ESP8266 project measuring distance with ultrasonic sensor, connecting to AWS IoT and Arduino IoT Cloud for remote monitoring and control.

This time measurement helps calculate the distance between the sensor and the object. Ultrasonic sensors are widely used in applications such as distance measurement, object detection, liquid level ...

Inside [Klaus]’ device is an Arduino Uno, an HC-SR04 ultrasonic distance sensor, and an Adafruit Wave Shield.

[Andy] demonstrates building an ultrasonic anemometer using a cheap after-market parking distance sensor kit and an Arduino. Demo video after the break.

The e-Health Sensor Platform was designed by Cooking Hacks to help researchers and developers measure biometric sensor data for experimentation, fun and test purposes.
