Data Logging

« Back to Water Sensors

Data loggers can help to record data from a sensor over time -- often over days or weeks, or even months. There are a variety of data loggers available, both commercial and open source. Each entry from a logger -- stored on, for example, a memory card -- may have a timestamp and some data loggers can record location from a GPS as well.

Data loggers can be paired with specific sensors, and an enclosure, as part of a test.

Design constraints

What are we trying to do that existing commercial data loggers don't do, or don't do well enough? We're looking for designs that optimize:

  • low cost (i.e. <$100)
  • easy to use
  • easy to build or buy
  • weatherproof (possibly)
  • waterproof (possibly)
  • Arduino-compatible (so that they're compatible with the huge Arduino ecosystem)

Options

Most of the below options are #arduino based, and all are open source:

Activities should include a materials list, costs and a step-by-step guide to construction with photos. Learn what makes a good activity here.


Power

How do you keep a data logger going in the field? Solar, big batteries, even run an extension cable out? We're developing resources on powering your data-loggers here.

Waterproof enclosures

The #riffle project -- and others -- have explored a lot of ways to make cheap waterproof enclosures for data loggers, but where wires and sensors can still stick out. Here are a some notes and prototypes under the tag #data-logger-enclosures. You can also visit the page on sensor enclosures here
