AI-enhanced optical spectroscopy revolutionizes food quality monitoring with rapid, non-destructive analysis, ensuring safety and reducing waste in production.

A team of engineers at Rice University has developed a tiny new sensor that could dramatically improve the safety of self-driving cars on public roads. This is a compact, low-power millimeter-wave ...

In recent years, integrated platforms equipped with microcontrollers (with Arduino probably being the best-known brand) have been gaining popularity.

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 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 ...

The OndoSense Apex Level Line enables high-precision and fast level measurements in harsh industrial environments with an accuracy of up to 0.1 millimeters via its combination of a high measuring rate ...

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 ...

On a snowy and slushy day across Greater Boston today, drivers might wish they had the advanced sensor technology coming to market soon from Boston startup Teradar. The company’s sensors work like ...
