This project was submitted by Ashok Ra in Make With Mesh: The Cypress & Digi-Key Bluetooth 5 IoT Design Contest Sponsored by Embedded Computing Design and was one of the winners! We are now posting it in the community for all of our developers to see what great things can be developed with the CYW20819 - as well as leverage some of the material to get started on your own design.

Project Name: Tire Pressure Monitoring System (TPMS) With Bluetooth Mesh
This Tire Pressure Monitoring System (TPMS) project set out to implement Bluetooth Mesh in a car, leveraging the 4 mesh nodes of the EZ-BT™ Bluetooth Mesh Development Kit on each of the 4 tires of a car. Each node streamed sensor data to a central hub which was a CYW20819 Arduino Eval Kit connected to a E-Ink Display. The data would be processed on the CYW20819 and then displayed on the E-Ink (can be seen from the images below). The video available (also below) shows how raising the temperate of the car via AC would change the sensor values being streamed to the hub via the CYW20819 based Mesh network (note: temperature sensor was used instead of pressure due to customs delivery issues).
