Fingerprint Sensor AS608 - A Beginner's Guide
One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →As one of the smallest systems around there are so many amazing things you could do with the Raspberry Pi if it was self-powered and portable. That’s exactly where the PiJuice comes it! A fully uninterruptible power supply HAT that will always keep your Raspberry Pi powered.
The revolutionary PiAnywhere technology contained in every PiJuice HAT - is the best way to take your Pi off the grid! The on board real time clock (RTC) will let your Pi know what time it is even with no power input or internet connection. Alongside this is an integrated microcontroller (MCU) chip which will manage soft shut down functionality and a true low power deep sleep state and intelligent startup.
You will be able to always keep track of the charge levels and other info with the two built-in RGB LEDs, trigger events and scripts with the three programmable buttons and since the PiJuice will use up to just five of your GPIO pins (just power and I2C), the rest are free to diversify your project. The stacking header allows you to continue to use your existing HATs and add-ons with the PiJuice.
