Engineering Notes
What we learn from real projects — sensor choices, comm trade-offs, field failures, and fixes that worked. No marketing, just notes.
How to Choose a Gas Sensor? Selection Guide
Sensor selection is one of the most critical engineering decisions in gas detection device development. Choosing the wrong sensor technology cannot be fixed by calibration — it leads to certification failures, false alarms, and high maintenance costs.
