The ESP32 does everything a Pi Pico does, but costs less and lasts 100x longer on batteries ...

Measuring the speed of a rotating object is a common requirement. Knowing the speed of table and ceiling fans, as well as ...

Abstract: This paper introduces an Arduino-based color-sorting conveyor belt system that automates object sorting by color. Employing a TCS3200 color sensor, an Arduino microcontroller detects red, ...

Researchers have developed a highly sensitive light-based sensor that can detect extremely low concentrations of cancer biomarkers in the blood. The new technology could one day make it possible to ...

Researchers in Sweden have unveiled a way to create high-performance electronic electrodes using nothing more than visible light and specially designed water-soluble monomers. This gentle, ...

An improved passive wireless sensor is presented for ultra-high temperature environments, utilizing a folded Complementary Split-Ring Resonator (CSRR) structure. A dedicated back-end circuit ...

Arduino library for the UFM02 ultrasonic flow sensing module through SPI, I2C, and UART from ScioSense. The UFM-02 is a complete unit including the sensor electronics, spool piece, connectors with ...

The SQUIRE project is taking quantum sensing into space, using advanced spin sensors aboard the China Space Station to search for mysterious exotic interactions that may reshape our understanding of ...

Presence/motion sensors are one of the best ways to make automations feel more natural, but most of them run on batteries and eventually have to be swapped. That’s one of the main reasons I really ...

Bats are nocturnal hunters and use echolocation to orient themselves by emitting high-frequency ultrasonic sounds in rapid succession and evaluating the calls' reflections. Yet, they have retained a ...
