Room Sensors App

• This app was made in Java for Android;
• Controls an LED and receives information from two sensors (humidity and temperature);
• Plots the information regarding the humidity and temperature and
• Sends notifications with alerts if the value from one of the sensors (or both) is outside the range specified by the user.

---

• The app communicates with the sensors and LED through MQTT;
• The plotted data is only available when there is a connection;
• The data is saved on Firestore;
• As of now, it only works until Android 12.

How to run

No apk is available

• Fork the repo and run it on Android Studio;
• The app can be run by changing the Firestore account with this tutorial;
• You can simulate the Arduino with the sensors and LED on the following MQTT sketch
• You can find the code for the sketch here

Examples

• LED on and temperature/humidity values of the sensors

• LED off and temperature/humidity values of the sensors

• Sensors min and max

• Alerts received

• Plot data
