The SparkFun Ultrasonic Distance Sensor - TCT40 (sen-24805) a user-friendly upgrade to the popular HC-SR04 sensor, offers non-contact distance measurement from 2cm to 400cm with an accuracy of 3mm.

Hue just did its biggest product launch ever as part of IFA 2025 and a key product is the new entry-level Essential smart bulb lineup. Though still not as cheap as some products you can find on Amazon ...

This is a library for the Arduino IDE that helps interface with ST's VL53L4CD time-of-flight distance sensor. The library makes it simple to configure the sensor and read range data from it via I²C.

Abstract: In this paper, we propose the use of ultrasonic sensors for autonomous parking systems. In general, LiDAR sensors are evaluated to be advantageous in autonomous parking systems, but this ...

Abstract: The present study designed the dual-point liquid level measuring sensor using the polymer optical fiber (POF). The sensor measures the liquid level variation based on the optical power ...
