Fun facts about the Hawksbill sea turtle:
- They get their name from their sharp, curving beak.
- Their shells change color slightly based on water temperature.
- They primarily eat sea sponges but also occasionally eat jellyfish and anemones.
Not-so-fun facts about the Hawksbill sea turtle:
- They’re currently critically endangered, mostly due to human impact.
Fortunately, students at the School of Science and Technology, Singapore, are on the case! The Perhentian Islands, formerly a large nesting ground for green and hawksbill sea turtles, now contain a turtle hatchery to boost declining turtle populations. The students needed to build a hardware system to constantly measure the temperature of soil at different depths in order to determine if incubating eggs in pails is as viable as incubating eggs buried under the sand.

The students developed a multitemperature sensor-based data-logging system that can be buried at different depths to measure the temperature of soil over a 24-hour period. The temperature sensors are connected to a multiplexer, NI myDAQ hardware, and a computer running NI LabVIEW software. The information gathered from this system will be used to help keep sea turtles around for future generations to enjoy.
