Proximity Camera

TEAM

Jennifer Toy, Ayush Gupta

MOTIVATION

We wanted to create a PCB that would interpret data from a proximity sensor and output to an LED display. The sensor has a resolution of 8x8 and would be directly displayed on an 8x8 LED matrix.

FEATURES 

Compute 

• Used ESP32 Micro-Controller to communicate with the VL53L5CX 8X8 Time-of-Flight multizone ranging sensor through I2C protocol

• Interpret serial data from sensor and output to LED display driver

• Used USB connection to upload the firmware

Sensing 

Proximity Sensing 

• Used a 8X8 Time-of-Flight multizone ranging sensor

Power

• Converting 5V input via USB protected by polyfuse and Schottky diode

• AP7215 LDO to convert to 3.3V

Actuation

• LED display :^)
