Project Description

This project implemented a very interesting mesh application that is sure to be product-ized in the near future, if not already. A plant Water Density Mapping System was created with the EZ-BT Bluetooth Mesh Development Kit. Capacitive Soil Moisture Sensors were attached to each Mesh Node and an enclosure around the Mesh Node was created to protect the PCB. These moisture-sensing mesh nodes were then placed in a plant pot. Through a mesh network, the moisture sensor data was collected at a proxy node (also one of the moisture sensing nodes) and streamed to a customized version of the Cypress Android Mesh Reference Mobile App.
