Nano Data Logger Kit from KAPtery

Regular price $39.00

This kit can be quickly assembled into a data logger which will save temperature and barometric pressure data to a microSD card. It comes complete with everything needed to start logging data (everything but AA batteries are included). The parts snap together so no soldering is required. A program is loaded on the Arduino Nano and will begin running and saving data as soon as the logger is turned on. This sketch can be downloaded here.

The data logger consists of an Arduino Nano and a shield which plugs into the Nano. The shield includes a slot for a microSD card (a 1GB or 2GB card is included) and a real time clock (DS1307) so all data saved has an accurate time stamp. 

A battery case for four AA batteries is included. It has an on/off switch and wires to connect to the screw terminals on the logging shield. Data can be logged continually for about two days on four AA batteries. The logger can also be powered with the included mini USB cable from a computer or the included DC adapter (phone charger, supplies 5v from wall power). For long-term operation on battery power, one of the Mini Pearl Loggers Kit (link) is a better choice.


A BMP280 sensor (3.3 volt operation only) is included for measuring the barometric pressure and temperature. Many sensors can be connected to one data logger. To connect more than one sensor at a time, a splitter or hub is required.


This logger is open source and like all Arduino based devices can be easily modified by adding additional sensors, LCD displays, indicator lights, relays, etc. The program loaded on the Arduino Nano can be easily modified and expanded using the free Arduino IDE . The easy solder-free connections make it possible to quickly try different configurations of sensors, indicators, and sketches while collecting real data with a reasonably sturdy device.


A guide to assembly and use of the Nano Logger can be downloaded here. Examples of how this data logger is used can be found on our website. Feel free to post comments on those research notes, or over on our main Q/A page if you have questions about the Nano Logger.
