The demonstration showcases a simplified version of a smart climate control system that collects sensor data from various IoT devices and sends it to a central location for analysis. The system uses Redis as the database to manage real-time IoT sensor data, specifically leveraging RedisTimeSeries to store and analyze time-series data. The application utilizes an NVIDIA Jetson Nano board, a Pimoroni BME680 breakout board, and Python scripts to read sensor data from the BME680 and send it to Redis for analysis. After setting up the Redis server, the application uses a transactional pipeline to populate the sensor data structure with temperature, pressure, humidity, and gas readings. The system also integrates with Grafana to create an informative dashboard that displays real-time sensor data.
