Qwiic GRID-Eye Infrared Array (AMG88xx) Hookup Guide
The Panasonic GRID-Eye (AMG88xx) 8x8 thermopile array serves as a functional low-resolution infrared camera. This means you have a square array of 64 pixels each capable of independent temperature detection. It’s like having thermal camera (or Predator’s vision), just in really low resolution.

Displaying Sensor Data with Bluetooth
In our previous Bluetooth tutorial called Sending Sensor Data Via Bluetooth, we showed how to display data from a triple axis accelerometer over the Arduino IDE’s serial monitor. Continuing off of the first tutorial, we are going to expand this project to include more capabilities for visualizing and interacting with your accelerometer data.
