[Trichl] creates a tiny GPS logger, identified as ‘TickTag’, that was intended as an low-cost place monitoring selection for animal research. The lower expense, little type aspect, and huge power density of the LiPo battery give the TickTag the capacity to track substantial populations of tiny animals, which include dogs and bats.
The TickTag was built with a LiPo battery specifically in head and promises 10,000 GPS fixes from a 30mAh mobile. Every single unit is outfitted with an L70B-M39 GPS module controlled by an Atmel ATTiny1626 microcontroller and sports a little AXE610124 10-pin relationship header for programming and communication. GPS details is stored on a 128kB EEPROM chip with each and every GPS site fix using 25 bits for latitude, 26 bits for longitude, and 29 bits for a timestamp. All it all up and you get 10 bytes for each GPS facts place (25+26+29=80), providing the 10k GPS fix higher sure.
To record higher top quality facts and prolong battery life, the TickTag can be programmed to history GPS location knowledge using variable frequency intervals or when geofencing bounds have been crossed.
Due to the fact the device is so smaller, any errant indicators shut to the antenna can result in complications with getting. [Trichl] warns that mounting the unit should be well away from any other tags or conducting material, together with its very own battery, which is expected to be mounted guiding the tag, not underneath, to prevent drowning out the GPS sign.
Having details off of the TickTag needs actual physical access to the device which can be finished by means of
a companion “user interface board”. The interface board integrates charging logic and USB conversation, among other functionality, lessening complexity in the TickTag module by itself.
All supply code, gerber documents, structure files, and 3d printed cases are out there on GitHub. Besides the documentation and resource code, their paper in the General public Library of Science (PLOS 1) journal is total of particulars, which include the benefits of embedding a product on a canis lupus familiaris.
Who is aware, possibly the TickTag is even resilient sufficient to be utilized to track the catus domesticus.
