Schluff is a yiddish word which means to take a short nap. This project is about finding the ideal environment for quality sleep by monitoring different conditions and biometric data. Ideally the data from this device would be overlayed with a wrist based fitness tracker for additional revelations. Schluff records the following: temperature, humidity, light, noise and heart rate. The collected data is sent from a Feather 32u4 (Arduino compatible) over to an iOS device or macOS laptop using BLE (Bluetooth Low Energy). The BLE catchers can save the data locally or relay it up to adafruit.io for storage and graphing.
The ESP8266 based Feather HUZZAH & the HUZZAH ESP8266 breakout are both very popular options for connecting projects to Adafruit IO. In this guide we are going to walk through the setup needed to get your ESP8266 up and running with the Arduino IDE & Adafruit IO. This same basic setup can be used as you progress through our Adafruit IO Basics series of guides.
Add Internet to your next project with an adorable, bite-sized WiFi microcontroller, at a price you like! The ESP8266 processor from Espressif is an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) and TCP/IP stack with DNS support as well. While this chip has been very popular, its also been very difficult to use. Most of the low cost modules are not breadboard friendly, don't have an onboard 250mA 3.3V regulator or level shifting, and aren't CE or FCC emitter certified....UNTIL NOW!
