The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

This is a DIY Arduino-based overcurrent relay project that emulates Inverse Definite Minimum Time (IDMT) protection using an Arduino Nano and ACS712 current sensor. Instead of traditional ...

Electro-optical detectors are used to measure or sense the radiation emitted or reflected by objects within the detector’s optical field of view (FOV). Passive systems operate without any illumination ...

Sony Semiconductor has revealed the LYT-901, which is its first 200MP smartphone camera sensor. The new sensor is larger and has larger pixels than Samsung’s 200MP sensors, suggesting improved image ...

Raspberry Pi launched a follow-up to its Camera Module 3 with the Camera Module 3 Sensor Assembly. Now, Raspberry Pi users can put the camera sensors into their own custom form factors. The move ...

The visible light spectrum that humans perceive spans only a small portion of the electromagnetic spectrum — roughly 430 to 750 THz, corresponding to wavelengths of ~400-700 nm. Just beyond this range ...

Neuroscientists and materials scientists have created contact lenses that enable infrared vision in both humans and mice by converting infrared light into visible light. Unlike infrared night vision ...

Over on his YouTube channel [Electronic Wizard] has released a video that explains how infrared (IR) remote controllers work: IR Remote Controllers protocol: 101 to advanced. This video covers the NEC ...

Relay Therapeutics has laid off about 70 employees, the biotech's third round of cuts in less than a year. The most recent workforce reduction, along with other restructuring efforts made over the ...

US defence giant RTX feels that advanced electro-optical/infrared (EO/IR) sensors are now well positioned for detecting unmanned air vehicles (UAVs), missiles, and aircraft at extreme ranges. In the ...

One of boxing's biggest stars returns to the ring on Saturday night when Gervonta "Tank" Davis puts his WBA lightweight title on the line against WBA junior lightweight champion Lamont Roach Jr. Davis ...

The NBA's 2025 All-Star Weekend has arrived. We saw the Rising Stars Challenge on Friday night and Mac McClung win the Dunk Contest for the third year in a row (and some Skills Challenge Controversy) ...
