In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

Back in 2024, Renesas first released the RA0E1, an ultra-low-power Cortex-M23 MCU designed for cost-sensitive applications, followed by the RA0E2, with ...

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 ...

Over the past decades, physicists and quantum engineers introduced a wide range of systems that perform desired functions leveraging quantum mechanical effects. These include so-called quantum sensors ...

About a year ago, my husband and I moved into our new home in the Parisian suburbs, a 2019 build with many large French doors across every room and floor. Those big windows-slash-doors bring a level ...

A dual resonator graphene sensor measures pressure with exceptional precision and stability, using built-in temperature compensation to maintain accuracy across wide pressure and temperature ranges.

Submitted by the Economic Development Council. Youth ages 10-14 are invited by the Economic Development Council in partnership with the Funhouse Commons on Orcas to participate in Arduino Coding. The ...

If you don’t think putting holes in pipes is a good idea, read on. Swedish company eMarine, which uses advanced monitoring and optimization technologies, to reduce vessel’s fuel consumption and ...

Abstract: This work proposes a compact Fabry–Perot interferometer (FPI)-type fiber-optic temperature sensor based on the high-order harmonic Vernier effect. The sensor is constructed by forming a ...
