Wearable Continuous Temperature Monitor
This armband continuously monitors body temperature while you sleep. You can monitor temperature hands-free from another device, even if you're in a different room.
You can monitor temperature for up to 8 hours on a full charge (tested on a 3.3V 400mAh lipoly battery, data sent to Adafruit IO once every minute). Data is sent to your Adafruit IO account for long-term storage and visualization. Use Adafruit IO Triggers to be notified by email when the temperature increases past a set threshold.
Bluetooth Low Energy (BLE) Temperature Armband
Monitor your (or someone else's) temperature, hands-free, from anywhere with the Adafruit Feather nRF52840.
Temperature readings are sent from the Feather nRF52840's Bluetooth-Low-Energy (BLE) radio to the Adafruit BLE Connect App.
Interactive Temperature Dashboard
Adafruit IO is the easiest way to stream, log, and interact with your data. This project uses Adafruit IO to log and display temperature data on an interactive dashboard. You can check the current thermometer reading and monitor the temperature over time.
Fever Email Alerts
If a temperature threshold is reached, your armband sends an email to your phone.
Hands-Free and Rechargeable
We've designed this wearable armband to hold a rechargeable 3.7V 400mAh lipo battery. The Feather NRF52840 has an on-board lipo charger - plug it into micro-USB to charge between uses.
