Real Time Temperature and Image Tweet Using Raspberry Pi & Twitter API

This IoT project integrates hardware sensing, visual data capture, and cloud communication using a Raspberry Pi 5 running Raspbian OS. At the core of the environmental sensing subsystem is the DS18B20 digital temperature sensor, which communicates ambient temperature data to the Raspberry Pi over a 1-Wire data bus protocol. Simultaneously, visual data is captured using the CSI Raspberry Pi Camera connected directly to the board's high-speed Camera Serial Interface port. Written in Python 3, a script orchestrates the entire sequence: it polls the DS18B20 sensor for the latest temperature reading, captures a snapshot image from the CSI camera, and packages both pieces of data together. Utilizing the Twython Python module, the script authenticates with the Twitter API using developer credentials from an active Twitter account. It then programmatically generates a status update containing the real-time temperature string alongside the newly captured image file, executing an automated HTTPS POST request to publish the payload directly to the social media platform. Through this continuous loop, the Raspberry Pi acts as an autonomous edge-computing node bridging physical environmental telemetry with internet-based communication channels.
