#lowcostsensors — Public Fediverse posts

I’m excited to be heading to Los Angeles next week for the Air Sensors International Conference (ASIC) 2026. I’ll be sharing new findings from our work evaluating low‑cost air sensors for data fusion.

Presentation: In-Situ Evaluation of Low-Cost PM2.5 Sensor Networks Using a Novel Distance-Based Method Quantifies Sensor Uncertainty and Reveals Episodic Variability in Performance
Session: Air Sensor Degradation and Operating in Challenging Environments
Time: Thursday, May 7th, 2026 | 1:30–3:00 PM

If you’ll be at ASIC, I’d love to connect and exchange ideas.

Two Bacteria Team Up for Electrochemical Signals

New E. coli bacteria can detect specific chemical pairs by making electricity. This could lead to cheap sensors for water testing and health.

Scientists have made E. coli bacteria that produce electricity when they detect certain chemicals together. This is like a tiny alarm system for pollution or disease.

Ah yes, because nothing screams "cutting-edge aerospace technology" like a 3D-printed rocket powered by a $5 sensor. 🚀💸 Clearly, the future of space travel involves bargain-bin sensors recalculating trajectories mid-flight, because who needs precision when you have GitHub! 😂

Enjoying the discussion of cross-validation methods for use of sensor data for air quality applications at the EPA air sensor QA workshop. It’s easy to overestimate how well you are doing with sensor data corrections or fusion applications unless a rigorous independent test approach is used #airquality #airpollution #crossvalidation #lowcostsensors @dwestervelt https://www.epa.gov/amtic/2023-air-sensors-quality-assurance-workshop

Introduction:
I’m an environmental engineer and professor at CU Boulder. I work with aerosols (tiny particles in air that are bad for you to breathe), especially in indoor air.
