Tiny GPS Logger For The Internet Of Animals
[Trichl] produces a tiny GPS logger, called ‘TickTag’, that was built as an reasonably priced location monitoring solution for animal scientific tests. The very low charge, very small variety variable, and large power density of the LiPo battery give the TickTag the capacity to monitor big populations of smaller animals, such as pet dogs and bats.
The TickTag was designed with a LiPo battery exclusively in brain and statements 10,000 GPS fixes from a 30mAh mobile. Each and every device is equipped with an L70B-M39 GPS module managed by an Atmel ATTiny1626 microcontroller and sports activities a very small AXE610124 -pin connection header for programming and interaction. GPS details is saved on a 128kB EEPROM chip with every GPS place fix employing 25 bits for latitude, 26 bits for longitude, and 29 bits for a timestamp. All it all up and you get 10 bytes per GPS info point (25+26+29=80), offering the 10k GPS take care of higher bound.
To history greater high-quality data and prolong battery existence, the TickTag can be programmed to record GPS spot facts employing variable frequency intervals or when geofencing bounds have been crossed.
Due to the fact the device is so small, any errant signals close to the antenna can trigger difficulties with acquiring. [Trichl] warns that mounting the gadget should be effectively away from any other tags or conducting content, like its own battery, which is necessary to be mounted powering the tag, not below, to stay clear of drowning out the GPS signal.
Having info off of the TickTag involves bodily entry to the system which can be accomplished by means of
a companion “user interface board”. The interface board integrates charging logic and USB conversation, between other performance, lessening complexity in the TickTag module itself.
All supply code, gerber information, style information, and 3d printed instances are available on GitHub. Aside from the documentation and resource code, their paper in the General public Library of Science (PLOS A single) journal is full of aspects, like the outcomes of embedding a system on a canis lupus familiaris.
Who is aware of, maybe the TickTag is even resilient plenty of to be made use of to keep track of the catus domesticus.
