Project - 3152

/*This is a project by Vrishak and Krishna Vemuri. This takes the temperature from the AMG8833 sensor and distance from HC-SR04. This corrects the temperature with the distance. Then, the pixels are shown on the SD card. The temperature is reported to NodeMcu, LCD, and SD card
**************************************************************************
  This is a library for the AMG88xx GridEYE 8x8 IR camera

  This sketch makes a 64 pixel thermal camera with the GridEYE sensor
  and a 128x128 tft screen https://www.adafruit.com/product/2088

  Designed specifically to work with the Adafruit AMG88 breakout
  ----> http://www.adafruit.com/products/3538

  These sensors use I2C to communicate. The device's I2C address is 0x69
