It operates without an operator and uses proximity sensing to trigger ... and Optical Engineering (ICPPOE 2023) showcased an Arduino-based digital infrared thermometer. This system, built with a ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors.

LILYGO T-Watch S3 Plus is an ESP32-S3 smartwatch with WiFi, BLE, and LoRa, gaining a GPS module and a larger battery against ...

The study investigates an emerging research field: the interaction between sleep and development. The authors use Drosophila larvae sleep as a study model and provide valuable insight into how ...

That proximity to power is perhaps even more significant in President Donald Trump’s second term, as chief of staff Susie Wiles has committed to running the White House — and limiting who has ...

Ever wanted your own X-ray machine? Of course you have! Many of us were indoctrinated with enticing ads for X-ray specs and if you like to see what’s inside things, what’s better than a ...

while the IR channel facilitates a stable output over a wide range of light sources. With an ambient light range from 0 lx to 176 klx, the sensor will not saturate in daylight, while its high ...

Yet, the physical nature of this fluorous effect is unknown. Here, we shed light on the fluorous effect by analyzing the infrared absorption spectra of perfluorinated and semifluorinated alkanes in ...

Designed a real-time LPG leakage detection system using an MQ-5 sensor and Arduino UNO. The system monitors gas levels and sends SMS/calls via a GSM module. Integrated a servo motor for automatic gas ...
