About the project

Each year there are many casualties in high altitude rescue caused due to hypothermia. To solve this problem, I want to develop a wearable device for hypothermia detection and body warmer.

Story

Each year there are many casualties in high altitude rescue caused due to hypothermia. To solve this problem, I want to develop a wearable device for hypothermia detection and body warmer. 

The proposed working:

1. Using the temperature sensor (PCT2075DP-ARD), we will monitor the body surface temperature.

2. When the body temperature is below the threshold temperature, then NXP i. MX RT MCU development board will activate heating pads attached to the body restoring the body temperature to normal.

There was a problem related to the usage of the  PCT2075DP-ARD with the MIMXRT1020 development board; the details are in the following link: https://community.nxp.com/t5/i-MX-Processors/Using-PCT2075DP-ARD-with-MIMXRT1020-EVK-Board/m-p/1277790#M174152

So, I have used a different temperature sensor in my project.

The pin reference for the  MIMXRT1020 development board is in the schematics files of the development board.
