Lidar systems use pulses of infrared light to measure distance and map a 3D scene with high resolution, allowing autonomous vehicles to rapidly react to obstacles that appear in their path. But ...

Working with multiple sensors on an Arduino can unlock richer, more interactive projects. By integrating motion, light, distance, and environmental readings, you can create systems that respond ...

The Raspberry Pi RP2040 microcontroller has inspired a wave of creative projects, from environmental monitors to laser distance sensors. With its low cost, flexible programming options, and rich ...

Abstract: The water level indicator project utilizes an Arduino Uno microcontroller, an LCD display, and a Bluetooth module to provide an efficient solution for monitoring water levels and controlling ...

Capacitive displacement sensors span a wide range of resolution, from the touchscreen sensors which can only detect displacement as a binary state, all the way to the sensors in semiconductor fabs ...

A thin diamond film encapsulates gold nanoparticles into a reusable SERS substrate that survives acid, abrasion, and months of storage without losing sensitivity. (Nanowerk Spotlight) Every molecule ...

This library (with example) is designed to be integrated in projects using ultrasonic proximity sensors. It was tested with HC-SR04 device but it should be usable with equivalent sensors which have a ...

Abstract: This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic ...

ST’s VL53L5CX is a very small 8×8 grid ranging sensor that can perform distance measurements at a distance of up to 4 meters. [Henrique Ferrolho] demonstrated that this little sensor can also be used ...

Dhruv Bhutani has covered the Android ecosystem since 2010, with a focus on smartphones, connected devices, and home networking. His reporting is informed by hands-on experience reviewing hundreds of ...
