All work
Filter by area if you're after something specific. Each project opens into a short case study covering the problem, what got built, and how it turned out.
Sensors track conditions inside a grain warehouse and stream them to a web dashboard, with prediction insights and measurement reports layered on top of the live readings.
NodeMCU firmware that reads a DHT11 and HTTP POSTs temperature and humidity to a hosted endpoint, which writes every reading to a database. A second, deliberately minimal sketch exists purely for testing POST endpoints.
An ESP32 unit measures temperature, humidity, and spoilage gases inside onion storage and streams them to a dashboard. A trained model turns those readings into a shelf-life estimate the farmer can act on.
A Top 5 team project. An MFRC522 reader authenticates the voter before four candidate buttons go active, LEDs and a buzzer confirm what happened, and a Node server feeds a React dashboard showing the tally in real time.
Ten self-contained IoT projects on the ESP32 DOIT DEVKIT V1, covering remote control, environmental monitoring, home security, safety alerts, gardening, parking, and RFID access.
