Project Description

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. Raising the temperate of the car via AC would change the sensor values being streamed to the hub via the CYW20819 based Mesh network.
