You only need a capable microcontroller and some off-the-shelf sensors, and you’re up and running. Continue reading “2025 One Hertz Challenge: An Arduino-Based Heart Rate Sensor” → ...

Inside, an Arduino Nano is hooked up to a series of WS2812b LEDs. The LEDs are flashed in time with the heartbeat of the person holding the heart, thanks to a MAX30102 heartbeat sensor.

An optoelectronic sensor IC from Osram Semiconductors can be used to monitor heart rate and blood oxygen levels. The BioMon optoelectronic sensor is available from distributor Intelligent LED ...

If you would prefer to build your very own DIY heart rate monitor, rather than purchase an expensive smartwatch or fitness tracker. You may be interested in a project published to the Hackster.io ...

Maxim has created a module for sensing human heart-rate and oxygen saturation that includes photodiodes, an analogue front-end and a Arm Cortex-M4 microcontroller with embedded algorithms, in a thin ...

Peloton has just launched a new forearm-worn heart-rate band that will replace the company's current chest-strap monitor. The $90 heart-rate monitor (HRM) uses optical sensors rather than the ...

At the heart is an Arduino compatible microcontroller (based on the Leonardo) with a few extras baked in, including a Freescale touch sensor connected to 12 electrodes and an audio processor for ...
