The quantified fish: an aquarium featuring @Raspberry_Pi #piday #raspberrypi

March 07, 2014 Jessica


The folks over at readwrite made this fun and easy project using Adafruit parts and a Raspberry Pi.

Dogs and cats get a lot of love on ReadWrite. Owen uses a fitness tracker to monitor his terrier. Adriana uses the Internet of Things to keep tabs on her cats while she’s at work.

As the owner of a betta fish, I didn’t think I’d also get a chance to join in on the fun. However, with the help of a Raspberry Pi, I found a way to make the world’s most low-maintenance pet even easier to care for than before.

The solution? A Raspberry Pi waterproof temperature sensor. With the help of the Pi, the thermometer delivers the exact real-time temperature to any computer on the local network that queries for it. The hack can even be set up to deliver the temperature to any computer on the Internet, provided you have a server configured to receive its requests.

This project required both hardware and software tinkering. I’ve never done any hardware hacking before, but I was able to make it work on the first try with a tutorial from Adafruit.

Adafruit Assembled Pi Cobbler Breakout + Cable for Raspberry Pi – Now that you’ve finally got your hands on a Raspberry Pi® , you’re probably itching to make some fun embedded computer projects with it. What you need is an add on prototyping Pi Cobbler from Adafruit, which can break out all those tasty power, GPIO, I2C and SPI pins from the 26 pin header onto a solderless breadboard. This set will make “cobbling together” prototypes with the Pi super easy. Designed for use with Raspberry Pi Model B AND Model A, both revisions. Read more.


Waterproof DS18B20 Digital temperature sensor + extras – This is a pre-wired and waterproofed version of the DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. Because they are digital, you don’t get any signal degradation even over long distances! These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems. Read more.
