Pseudo-Medical Monitor

Pseudo-Medical Monitor for Christmas Cheap Gift

In preparation for the expected Christmas Gift availability crisis, I present the Pseudo-Gift of the season. The time honored tradition of knockoff products hitting the market before Christmas is alive and well. What better than a multi-property knockoff device? Star Trek / Arduino / Medical knockoff device gift for everyone. This Pseudo-Medical Tricorder ripoff is the stocking stuffer for 2021.

Operations

• Thermal Image from AMG8833 Sensor.
• Ambient and Object Temperature from MLX90614 Sensor.
• Distance of device from user via VL53L0X Laser TOF Sensor.
• Pulse Rate from MAX30102 Sensor
• Fingerprint Scan image capture from Capacitive Sensor with ID809 processing capabilities.
