I´m learning about Arduino, and I am practicing with some sensors.

Some students ask me about a circuit for measurement of pression, humidity and temperature, and buy a BME280.

I proposed for they, make this circuit sending data for a smartphone. next step was build the app using MIT App Inventor and adjusting the sketch base.

EXPANDED TECHNICAL DETAILS

Mobile Atmospheric Telemetry hub

A portable and efficient weather station that streams environmental data directly to your smartphone dashboard over a wireless Bluetooth link.

  • Multidimensional Sensor Acquisition: The Arduino captures Temperature and Humidity (via DHT series) and Barometric Pressure. The firmware calculates the relative "Heat Index" locally before transmission.
  • BT Serial Command Handshake: The user's phone app sends a "POLL" command. The Arduino responds by sending a single, comma-separated data packet (CSV) containing all the current weather readings.

Interaction

  • Live Mobile Data Plotting: Perfect for field research; the smartphone app can log and graph the incoming Bluetooth weather stream in real-time, allowing for immediate environmental analysis.
