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 ...

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 ...

Wherever hydrogen is present, safety sensors are required to detect leaks and prevent the formation of flammable oxyhydrogen gas when hydrogen is mixed with air. It is therefore a challenge that today ...

Hydrogen plays an important role in society’s energy transition. For the technology to be used on a broad scale, effective hydrogen sensors are required to prevent the formation of flammable ...

Abstract: This article proposes a temperature-humidity assembled sensor based on AlScN surface acoustic wave (SAW) technology for simultaneous monitoring of temperature and humidity. The assembled ...

United States Customs and Border Protection is paying General Dynamics to create a prototype of “quantum sensors” alongside a “database with artificial intelligence” designed “to detect illicit ...

Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

Another of IKEA’s new smart home products is now available in the US. You can now purchase the TIMMERFLOTTE temperature and humidity sensor online. The TIMMERFLOTTE is available for $9.99. IKEA is ...

With Christmas a little over two weeks ago, one might be scrambling to find a gift for a loved one, friend, or family member. If you’re familiar with Arduino or Raspberry Pi and have a free weekend, ...

DES MOINES, Iowa—For over a decade, a network of water quality sensors managed by the University of Iowa has provided publicly available data about waterways across the state. And while Iowa grapples ...

The “Neuron” sensors—made by Norway’s Heimdall Power—collect live data on temperature, current, sag, wind, and weather, helping operators safely push more power through existing lines. The project, ...
