In this article, we will learn how to similar speed sensor using Arduino and IR sensor. By setting up the two IR sensors at a fixed distance from each other, we can track the time it takes for the ...

Arduino UNO: As you know that Arduino is a microcontroller-based open source electronic prototyping board that can be programmed with an easy-to-use Arduino IDE. The UNO is one of the most popular ...

Bethea, R. M., and Wheelock, T. D., Abstracts of the 2nd Biannual International Gas Chromatography Symposium, 1 (published by the Instrument Society of America ...

This module is based on the I2C light-to-digital converter TSL2561 to transform light intensity to a digital signal. Different from traditional analog light sensor, as Grove - Light Sensor, this ...

THIS CODE IS OBSOLETE * It needs to be updated to be compatible with changes to the ESP32 standard libraries. Also, if fine granularity control is required, it needs to use long int arithmetic instead ...

They will also be able to estimate your heart rate while in the water, which is very useful for tracking your workouts more comprehensively. The most expensive entries here also contain dive ...

Wearables are getting serious about health, and the use of health and wellness features, such as heart-rate monitoring and pulse-oximeter tracking, has become increasingly popular. But why measure ...

'ZDNET Recommends': What exactly does it mean? ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources ...

While the cEDA sensor measures responses, the stress score uses estimates from heart rate and sleep data. It uses a 0-100 measurement, and low scores can highlight the need to pay attention to ...
