Here is a kit of components designed to environmental data exploration. If you can log data (write to a file) like pressure variation at floor level, this kit was made to learn the variation of pressure and temperature vs altitude.
The pressure diminue as the altitude increase (take a look to our article about the PNM pressure - pressure normalised at sea level)
This kit allows you to create an introduction workshop with an overview of basic input/ouput with Arduino to switch followed by a data capture + data logging session.
Some soldering operations should be foreseen (See also this "Soldering training kit" if you need to train about soldering).
- Installing Arduino
- First step - Blink the board LED wired on the pin #13
- Wire and control an external LED
- Use the Serial Debugger - See the messages sent with Serial.println()
- Detect the pressure on a button
- Software unbouncing (for inputs like button)
- Turn off the red LED when the button is pressed
- Blink the green LED (5 times) when the button is pressed. The Red LED must be switch off during green LED blinking.
- The TMP36, temperature sensor with analog output
- The BMP280, barometric senseur - display the pression and temperature
A first introduction to advance I2C bus sensor
- DataLogger Shield - initialize the real time clock
- DataLogger Shield - Write environemental data on the SD Card
- Use the CSV file format (basic tabular data storage for spreadsheet software)
- The TMP36 temperature data
- The BMP280 pressure and temperature data
- Reuse the saved data in spreadsheet - graphical display
This kit is composed of the following:
