Concept
Throughout the design process of the DS3231 and the Arduino Data Logging Shield, another data logging device caught our attention.
This design uses the Arduino Nano and a data logging shield. The necessary parts are all included in a kit from Kaptery (http://kaptery.com/) that cost $29.
Included in the kit:
- Arduino Nano with the logger shield
- BMP280 sensor that measures barometric pressure and temperature
- 1 GB MicroSD card
- A case for four AA or AAA batteries
- AC-DC converter supplies 5 volts from wall power
- USB type A to mini USB power/data cable
- 4 connecting wires
- CR1220 coin cell battery for real-time clock
Build
We decided to test this third logger because of its feasibility, user-friendliness, and cost.
The build of this circuit was quick and easy.
Here is an image of our completed setup.
With the help of the detailed instructions seen above, after only 4 short steps, the Nano data logger was ready for initial testing.
