Released under The MIT License, see LICENSE.txt file for more details

Built with

• Raspberry Pi 1 Model B
• USB power adapter for the Pi
• GrovePi+ board (firmware version 1.2.7)
• Grove RGB LCD display
• Grove temperature and humidity (DHT) sensor or Grove temperature and humidity (DHT) Pro sensor
• Grove air quality sensor
• Lego bricks for the case

Setup

It is expected that you have already set up GrovePi on your Raspberry Pi.

1. Connect the display and both sensors.

• Connect the display to the port I2C-1.
• Connect the DHT sensor to the port D7.
• Connect the air quality sensor to the port A0.

2. Download the python script.
3. Depending on which DHT sensor you are using, you have to adapt the value assigned to DHT_SENSOR_TYPE at the beginning of the script. Its comment explains more.
4. Run the script: python air-quality-measurement-system.py
