Padiku

Bringing a community rice dryer's monitoring and controls to the web.

I designed the web interface and configured the MQTT/server path between the application and dryer controller.

System overview

Input
Temperature, humidity, machine status and control requests
Processing
ESP8266 connectivity, MQTT messaging and server logic
Output
Web monitoring and requests sent toward the dryer; local controls remain available

I worked on the software path with hardware and electrical teammates, who built the machine and power system.

Path System behavior and my work
Device to web MQTT and server logic carry temperature, humidity and machine status toward the application. My work: configured the MQTT/server path and integrated controller communication.
Web to device The server routes control requests toward the dryer controller while local controls remain available. My work: coordinated the request path with the hardware and electrical teams.
Web interface The later web interface used React and Vite for monitoring and control views. My work: designed the web interface.
Integration The team checked incoming readings and outgoing control requests over Wi-Fi. My work: coordinated testing with the hardware and electrical teams.

Integration status and lesson

We tested incoming readings and outgoing control requests over Wi-Fi. Residents could operate the dryer.

The integration depended on a shared understanding of each reading and control request across software, hardware and electrical work.
