Building an occupancy sensor with a $5 ESP32 and a serverless DB
Summary: Matt's Blog discusses building an occupancy sensor using a $5 ESP32 and a serverless DB to collect occupancy data across a college campus. The project aims to track occupancy metrics with a Bluetooth beacon and analyze the data to predict trends. The author tests various devices and finds the XIAO ESP32C3/S3 to be the most reliable. The data collected shows trends in student movement, making it suitable for time series forecasting. The project raises questions about the accuracy and privacy of using BLE beacon counts as a proxy for actual population count and potential improvements to the system.
