Build a DIY ESP32 LoRaWAN sensor node to track garden temperature and humidity from up to 600 meters away. Includes PCB ...

Researchers at the University of Arkansas and the University of Michigan have reported the creation of a graphene-based ...

Don’t let a flat tire deflate your drive. Check out our roundup of top-rated tire pressure gauges for every ride.

The air around us rarely announces itself. Exhaust from a busy road, dust from a building site, smoke from burning leaves, fumes from a kitchen, or a closed ...

Air sensors, especially networks of air sensors, can produce large volumes of data that must be wrangled, harmonized, processed, and visualized to help users gain insights into the air quality data ...

In my early ESP32 tinkering days, I’d only use the microcontroller to test with LEDs, resistors, and other circuitry components. In fact, writing simple C++ programs to perform basic tasks on the ...

Wearable sensors coupled with AI can generate blood pressure readings nearly as accurately as the invasive and risky arterial lines relied on in intensive care units and operating rooms, new work by ...

Air sensors—also called portable, low- or lower-cost air quality sensors or sometimes “monitors”—have made it easier for people to monitor the air quality where they spend time. Because they provide ...

Connecting sensors to Arduino opens up a vast array of possibilities for hobbyists and professionals alike, transforming ideas into functional prototypes and projects. Whether you want to measure ...

A common component of a control strategy for a recirculating AHU with a return fan is the incorporation of a relief air plenum pressure sensor. This sensor is sometimes used for monitoring only, but ...

Air quality sensors play a crucial role in maintaining a healthy indoor environment, especially in homes where air quality can fluctuate due to factors like cooking, cleaning, or outdoor pollution. In ...
