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 ...

Abstract: Radar technology has been a cornerstone of numerous applications, from aviation to meteorology, offering invaluable capabilities for object detection and tracking. Traditional radar systems, ...

10th February 2026: We added new Steal The Brainrot codes. If you've played another astoundingly popular Brainrot game bearing a similar title, you'll probably feel right at home playing Fortnite ...

A new technology has been developed that enables cuffless non-invasive blood pressure monitoring by using ultrasonic to track real-time changes in vascular diameter-without the need for a traditional ...

30th November 2025: We added new Last Letter codes. If you can imagine doing one of those speed typing tests, but every single time you failed to type "xylophone" quick enough, a guy dressed as Goku ...

Have you ever wondered how a robot navigates a cluttered room or how a drone maintains its altitude with pinpoint accuracy? The secret lies in the tools used to measure distance, an often-overlooked ...

Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...

As robots increasingly enter human spaces, robotics companies will need to think about safety differently than they did when robots were largely siloed from their human counterparts. Sonair thinks its ...

The SparkFun Ultrasonic Distance Sensor - TCT40 (sen-24805) a user-friendly upgrade to the popular HC-SR04 sensor, offers non-contact distance measurement from 2cm to 400cm with an accuracy of 3mm.

RPS-429AA-40P-IS2 intrinsically safe (IS), ultrasonic sensor achieves precise accuracy in distance measurement and object detection applications. With ATEX, IECEx and C-UL-US certifications, this ...
