IoT enabled smoker for great BBQ
summary
A working IoT smoker is built: a RasperryPi and AWS Greengrass device reads a food thermistor via an MCP3008 thermistor probe, sends data to AWS IoT Core then into an event-driven serverless stack using SQS Lambda EventBridge Step Functions S3 and DynamoDB. The system implements stall detection and fire alerts, stores raw messages first, augments events with thresholds, and triggers notifications. Demonstrated improvements to temperature control and deployable device updates over the cloud.
