LED switch on in order when an object is getting closer.
Smart bin that monitors waste bin air quality, level, temperature, and humidity.
Calculate distance to a certain object using an ultrasonic sensor. It can be used for car distance alerts, security systems etc.
Use Particle Mesh boards to collect data from all over a house. The data is then aggregated into the Particle Cloud.
Just a quick showcase on a handheld, wireless and battery operated distance sensor. Incredibly long-life (8 + years!).
This shows how to use the distance sensor.
Lets talk about this Sharp Distance Sensor
The ultrasonic sensor detects objects and lights up Red, Yellow or Green LED based on its position.
Distance measurement using an ultrasonic sensor.
Hold you hand near the box and it will open automatically.
Creating an adjustable distance parking sensor using a GrovePi+ board, an ultrasonic ranger, two LEDs, buzzer and and RGB LCD Display.
Arduino project to display distance on a SSD1306 OLED.
Use an ultrasonic module HC-SR04 distance measuring ranging sensor on your BeagleBone Blue.
Quick and easy project to teach kids how ultrasonic sensors measure distance. Distance is shown on a mechanical dial - servo motor.
Project of water level monitor with ultrasonic sensor HC-SR04 with implementations for Arduino + Ethernet, ESP8266 or ESP32 microcontroller.
Radio link two micro:bits and a 'sonar' ultrasonic distance sensor. Detect movement with one and immediately show an alert on the other.
It can be used in areas without a high demand for accuracy, such as obstacle avoidance for robots and distance detection alarms.
