Here are some rough notes on how I built a DIY ultrasonic distance sensor that communicates via Zigbee to Home Assistant running Zigbee2MQTT. I use this to measure the water level in my rainwater tank ...

If you do not know about LED and ultrasonic sensor (pinout, how it works, how to program ..), learn about them in the following tutorials: -Arduino-LED tutorial ...

VCC This pin is used to supply power to the sensor. It typically requires 5V DC power supply. Trig (Trigger) This pin is used to send a trigger signal to the sensor. When a HIGH signal (usually 5V) is ...

[Klaus] wanted some sort of aid for parking his car, and after running across a $4 ultrasonic sensor, decided to build his own speaking distance sensor (.de, Google Translation). Inside [Klaus]’ ...

The main goal of this application is to design an ultrasonic qualitative distance estimation sensor using Dialog Semiconductor’s SLG47105V. The system is designed using high-voltage (HV) macrocells ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...
