Sensors – Cave Sensor

Cave Sensor

The new Environmental Monitoring Sensor Module is an advanced daughterboard developed for the Single Node product line. Designed to endure the rigorous cave environment, this next-generation module integrates state-of-the-art sensors offering higher accuracy, extended functionality, and significantly reduced costs. With a robust stainless-steel encapsulation and enhanced firmware compatibility, this module supports long-term environmental data acquisition with increased precision and resilience.

This redesign was prompted by component availability issues and the discovery of superior sensors on the market, resulting in a complete overhaul of the daughterboard system architecture and software stack.
