title = "Cave pearl data logger: A flexible arduino-based logging platform for long-term monitoring in harsh environments",
abstract = "A low-cost data logging platform is presented that provides long-term operation in remote or submerged environments. Three premade “breakout boards” from the open-source Arduino ecosystem are assembled into the core of the data logger. Power optimization techniques are presented which extend the operational life of this module-based design to >1 year on three alkaline AA batteries. Robust underwater housings are constructed for these loggers using PVC fittings. Both the logging platform and the enclosures, are easy to build and modify without specialized tools or a significant background in electronics. This combination turns the Cave Pearl data logger into a generalized prototyping system and this design flexibility is demonstrated with two field studies recording drip rates in a cave and water flow in a flooded cave system. This paper describes a complete DIY solution, suitable for a wide range of challenging deployment conditions.",

The authors would like to express gratitude to the following for field logistics support and friendship: Rio Secreto Nature Reserve “family” at large—Tanya Ramirez, Otto von Bertrab, Fernanda Lasses and the many great guides; Bil Phillips of Speleotech; Centro Ecologico Akumal (CEA) with Gabriel Sanchez Rivera, Ivan Penie and Marco Montes Sainz; Natalie Gibb, Vincent Rouquette Cathala and Rory O{\textquoteright}Keefe of Under the Jungle; Gosia Pytel and Jeff Clark of Tulum Scuba; Olmo Torres-Talamante of Razonatura; Jen and Bart Smith and all the great staff at Akumal Bakery and Tortuga Escondido; Stacey Chilcott of Green Collar Productions and Monika Wnuk for making us look great; and Hackaday.io for the recognition with reaching the semi-finals in 2015. The students in the Northwestern University EARTH 360–Instrumentation & Field Methods classes and Aubri Jenson (Texas State University), have been very patient testers of build plans and code. Finally, we thank all members of the open-source community as their ongoing work enabled this project at several key stages. In particular: Massimo Banzi et al. for the creation of the Arduino platform; Nick Gammon for his excellent online tutorials and the Arduino community at www.arduino.cc and beyond.
