• Humidity
• Pressure
• Temperature
• Compass

Also the sense Hat has:

• a led matrix
• a joystick (not used in that example)

This project has two parts:

• Hardware testing
• A Sensor node (IoT) rest server using web.py

The hardware used on the Rest server are:

• Humidity
• Pressure
• Temperature

Project dependencies

The project use the python module sense_Hat that you can install on debian:

sudo apt-get install sense-Hat

Also, this project use web.py as a web server for building an API rest.

pip install web.py

How to use

To start the web server

python rest_server.py [PORT]

The web server automatically starts using your private ip and not the local host. The default port is 8080

The Rest server has 4 calls:

• humidity
• pressure
• temperature
• all_sensors

For example

http://ip:8080/humidity

The response is in JSON format:

{"code":200,"status":"ok","sensor":"[type_sensor]","value":[sensor_reading_value]}
