Live Sensor Dashboard

About Project

This project is a Wi-Fi–enabled temperature and humidity monitoring system built using the Wemos D1 Mini WiFi and a DHT11 sensor. The setup is powered directly from a computer via USB.

The D1 Mini reads real-time temperature and humidity data from the DHT11 sensor and transmits it over Wi-Fi to a ThingSpeak channel
using HTTP requests. ThingSpeak serves as a cloud-based data logger, storing each new reading and making it accessible through its API.

This webpage is connected to that same ThingSpeak channel. It retrieves the latest sensor data at regular intervals
and updates both the gauges and the live line chart automatically. The gauges display the current temperature (°C) and humidity (%), while the chart tracks changes over time.

Together, this system provides a clear, live visualization of the temperature and humidity in whatever room it is currently in.

The next step to this is to design a custom PCB board to integrate all the components neatly onto a single compact circuit.
I have no idea how to do this just yet, but, once that’s complete, the plan is to 3D print a custom enclosure to protect the electronics and make the device portable.
The final goal is to have a portable unit so my girlfriend can easily monitor her plants’ growing conditions in real time.
