Step by Step Tutorial for a Deluxe Data Logger

NewImage

Really well done tutorial by Adafruit customer Lucky Resistor – check out the full step-by-step build here.

PREFACE

I started the data logger project, because I tried to figure out if I can store my documents down in the root cellar. The humidity in this cellar varies from 75% up to 90% which is way to high for paper documents. So I plan to store the documents in a sealed box. Because I am not sure if the sealing is good enough for the environment down in the cellar, I will first place a “test box” there with the data logger inside.

There are plenty commercial data loggers available to use for this kind of task, but it is much more fun to build a own.

PROJECT PHASES

To test all involved components I first created a prototype on a breadboard. Then I created a minimal and simple version without display and just the sensor. The documentation for the minimal and simple version are still available on this site. After all tests were successful I built the final version with a nice case, display, capacitive keypad and wireless charging…

OVERVIEW

The data logger deluxe ist a humidity and temperature data logger. It is powered by a lithium ion battery which can be recharged wirelessly using a Qi charger. The data from the sensor is stored in a FRAM module. There is a small display and a capacitive touch key pad to control the device.

SHARP Memory Display Breakout – 1.3″ 96×96 Silver Monochrome: The 1.3″ SHARP Memory LCD display is a cross between an eInk (e-paper) display and an LCD. It has the ultra-low power usage of eInk and the fast-refresh rates of an LCD. This model has a matt silver background, and pixels show up as little mirrors for a silver-reflective display, a really beautiful and unique look. It does not have a backlight, but it is daylight readable. For dark/night reading you may need to illuminate the LCD area with external LEDs. Read more.

  1. This is a great project- well done. I realise you have the parts list posted that I could add up myself, but it’s easier to just ask what the total cost of your datalogger was. Thanks 🙂
