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 ...

Sometimes, it’s time to shut down the oscilloscope, and break out the cardboard and paints. If you’re wondering what for, well, here’s a reminder of an Instructable from [CrazyScience], that brings us ...

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 project is an adaptation of the original esp32c6_zigbee_ultrasonic_distance_sensor by Aralox (many thanks to him) to support the RS485 version of the sensor. Aralox did all the work and this ...

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 ...
