The hardware setup shown below includes the Arduino Uno R4, a DHT11 sensor, and the built-in Wi-Fi for email alerts. The DHT11 is connected with VCC to 5V, GND to ground, and the data pin to Digital ...

The sendEmail () function is responsible for triggering the email alert when an object is detected. A secure Wi-Fi client is ...

The IM19 is used in conjunction with the UM980 GNSS receiver to provide tilt-compensated Lat/Lon/Alt readings with 1cm accuracy up to 30° tilt angle, and 2cm accuracy up to 60°. Various bits of the ...

This all-purpose presence sensor is a master at monitoring indoor activity and linking it to smart home features you already use. Tyler has worked on, lived with and tested all types of smart home and ...

Aqara has announced the Spatial Multi-Sensor FP400, a new presence sensor that it says is precise enough to suss out whether you’re sitting, standing, or lying down. The FP400 builds on several past ...

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 ...

America’s grand strategy is in turmoil. Over the past decade, power shifts, territorial disputes, and the faltering of international institutions have fueled an increasingly heated debate about what ...

This Arduino example code demonstrates how to set up and use the IQS323 Integrated Circuit (IC). The IQS323 is a 3 Channel Self-Capacitive / 3 Channel Mutual-Capacitive / 2 Channel Inductive sensing ...

Infrared devices have become increasingly popular in recent years and can be found in many gyms to reduce muscle pain and inflammation. There are also many at-home infrared light devices for muscle ...

Extending its portfolio of image sensors for automotive applications, Sony Semiconductor Solutions Corp. has announced the upcoming release of its new 5-megapixel (MP) IMX775 CMOS RGB-IR image sensor ...

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 ...

Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light. Lenses are the most widely used ...
