Particle Sensor Breakout MAX30105 Heart rateSpO2 ...

The SparkFun MAX30105 Particle Sensor is a flexible, powerful sensor enabling sensing of distance, heart rate, particle detection and even the blinking of an eye. The MAX30105 has been equipped with three LEDs as well as a very sensitive photon detector. The idea is to pulse the different LEDs, then detect what shines back.

Evaluation of Three Sensor Types for Particle Motion ...

Particle motion can be measured directly using vector sensors or calculated from pressure gradients. This article compares three devices that measure particle motion: a threeaxis accelerometer, a threeaxis velocity sensor, and two 4element hydrophone arrays. A series of sounds (constantwave tones, white noise, and Ricker wavelets) were ...

Learn how to use these sensors for your ... Particle Blog

Feb 20, 2019· I used a Gravity Digital PIR (Motion) Sensor. “This is a PIR (passive infrared motion) sensor designed to work with Arduino and Raspberry Pi. It allows you to sense motion, it is commonly used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, lowpower, easy to use and don’t wear out.

How to use a PIR sensor General Particle

Mar 14, 2017· One tip is usually to power the PIR sensor from VIN to get 5V. Also make sure not to enable PULLUP or PULLDOWN on the INPUT because enabling it will make the GPIO not 5V tolerant. Make sure that your PIR sensor supports 5V as well. I have a webhook listening to “officemotion” and forwarding on the datato a push notification.

Mailbox Motion Sensor Particle Projects

Nov 21, 2019· We created a motion/light sensor that will let you know in real time when your mailbox opens. This is done using two Particle Argons and some fancy circuitry. One argon with the light sensor sits in the mailbox and the other argon sits at home in your bedroom, living room, etc. When the maildoor is closed the beam of light is broken.

This setup is designed to only show the room as available if no motion has been detected for 30 seconds. Try putting a blanket over the sensor to completely block all motion. Check your Particle webhook and make sure the event name matches the event name in the code. No motion is being detected (the D7 LED isn''t turning on at all).

US7999946B2 Fiber optic particle motion sensor system ...

A sensor apparatus combines an optical sensor in which acceleration, acoustic velocity, or displacement (vibration) causes a corresponding shift in the center wavelength of the sensor output, coupled to a high speed interferometric interrogator, through an unbalanced fiber interferometer. The unbalanced interferometer functions to translate optical wavelength shift into phase shift, which is ...
