Smart Museum Preservation System (IoT, Raspberry Pi, MQTT, Dashboard)

I am looking for a freelancer who can assist with both hardware and software development. The project involves Raspberry Pi setup, BME280 sensor wiring, GPIO configuration, MQTT communication, buzzer and 5V fan control, dashboard development, testing, troubleshooting, and documentation. I will have the hardware components, but I require guidance on circuit connections, pin assignments, software development, and system integration.
