NEXUS Project: Environmental Intelligence for Bioacoustics
A Citizen Science Initiative – 2026 Validation Phase
The Mission
Capturing a bat call is one thing — understanding the environmental context is another. Project NEXUS was born from the need to synchronize high-fidelity bat recordings (via TeensyBat) with precise micro-climatic data. We aren't just looking for flight "traces" — we are building a 4D picture of bat behavior in its natural habitat.
The Hardware Stack (Current Validation Build)
- MCU: Seeed XIAO ESP32-S3 Sense (Expansion board setup)
- Environment: BME680 (Gas, Humidity, Pressure, Temperature)
- Positioning: AIR530 GPS Module
- Climate Data: SparkFun Weather Station (SEN-15901)
- Analysis Pipeline: ML-based species identification via BatDetect2
- Visual Validation: TOPDON TS004 Thermal Imaging
Core Concept: The "Acoustic Bubble"
The "Acoustic Bubble" is our framework for correlating ultrasonic vocalizations with real-time environmental variables. By mapping temperature gradients and barometric shifts directly to specific detection events, we aim to understand how bats navigate micro-climatic changes.
Project Roadmap & Status (Spring 2026)
- NEXUS Core: Currently in the Active Validation Phase
- NEXUS-Cave (Concept): Under development — researching UV and thermal detection patterns
- NEXUS-Forest (Concept): Under development — planning LoRaWAN networking for remote monitoring
Why Open Source?
As a Citizen Scientist and mechanical professional, I believe transparency in hardware and data is key to protecting our natural legacy.
About the Researcher
My journey into bat research didn't start in a university lab. It started with curiosity — first photography, then the realization that the night holds an entire acoustic world invisible to most people. Bats became my window into that world.
What I bring to this project isn't a PhD — it's decades of engineering discipline, a deep respect for methodological rigor, and the patience to iterate until something works. NEXUS is the result of that approach: built from scratch, tested in the field, and constantly refined.
I believe that meaningful science doesn't require institutional affiliation. It requires honesty, precision, and a willingness to share what you find — even when the results are unexpected.
Get in Touch
I am always open to exchange with researchers, fellow bat enthusiasts, and developers working on acoustic monitoring or environmental sensor fusion. Whether you want to discuss methodology, share data, or explore collaboration — feel free to reach out via the blog or leave a comment below.
