Cozy Cam (Thermal Imaging Baby Monitor)

As my wife and I were expecting our first child, the engineer in me wanted to see if I could channel my excitement and nervousness into a productive engineering project, and the Cozy Cam was born! As I began to research baby monitors for my child, I noticed the premium price tag associated with products that were able to offer parents advanced features such as temperature and breathing monitoring.

I thought it might be fun to try to design my own! Based around the ESP32 family of microcontrollers, and the ESP-NOW communication protocol, the COZY CAM system consists of a transmitter and receiver. The transmitter is tasked with interfacing with a low resolution 32x24 pixel thermal imaging sensor. This image is then converted to a numerical matrix, and down sampled to an 8x8 grid of data. This data is then transmitted wirelessly via ESP-NOW to a receiving ESP32 that reads the matrix, applies a custom logistic regression machine learning algorithm to detect any health anomalies indicated by the thermal image, then displays the thermal image on an 8x8 RGB LED Matrix!
