Adafruit Optical Fingerprint Sensor

All-in-one fingerprint sensors make ID easy

Secure your project with biometrics - this all-in-one optical fingerprint sensor will make adding fingerprint detection and verification super simple. These modules are typically used in safes - there's a high powered DSP chip that does the image rendering, calculation, feature-finding and searching. Connect to any microcontroller or system with TTL serial, and send packets of data to take photos, detect prints, hash and search.

LED Breath Stats Mask

Build a Mask that Displays Breath Stats

by Michael Sklar

Combining Adafruit’s CCS811 gas sensor with a Circuit Playground Express and two NeoPixel Sticks we can quickly put together a mask that displays our breath attributes. This setup will monitor temperature, carbon dioxide, and total volatile organic compounds. The sensor is easy to work with using its I2C interface and pre-calibrated ranges. A mask is an ideal wearable as it provides a place to house the electronics as well as an option for continuous monitoring as it is a hands-free device that could be adapted for exercise or sleep. The gas sensors TVOC monitoring can be used as an indicator of ketosis as it will detect acetone levels on the breath which is a by-product of producing ketones. CO2 levels can also be a helpful indicator of how much glucose is being burned versus fats.
