End-to-end IoT sensor data live visualization and a Cooler / Heater control using AWS IoT Cloud.

This project is to capture temperature and humidity data from a BTREE IoT SENSOR and send it to a DynamoDB table in AWS cloud server and simultaneously display a live chart on a website url using AWS IoTcore, AWS DynamoDB, AWS S3 website, NodeJS and ChartJS. It also controls a Cooler and a Heater automatically based on the current values of temperature and humidity
