Selection Support
A faster route from
requirement to module shortlist.
Use this lightweight engineering checklist before sending your inquiry — better inputs produce a useful recommendation within 1 business day.
Selection Method
Target → principle → output → environment.
The fastest path to a useful quote is a clear definition of what the final device needs to detect and how the sensor connects.
Target gas or parameter
CO₂, PM2.5, VOC, HCHO, CO, H₂S, NH₃, O₃, SO₂, CH₄, O₂, T&H — narrows product family and module form.
Expected detection range
e.g. 0–5,000 ppm CO₂, 0–500 µg/m³ PM2.5, 0–10 ppm H₂S. Affects principle choice (NDIR vs electrochemical).
Sensing principle
NDIR / electrochemical / MOS / laser-IR / capacitive. We'll recommend if you're unsure — share final device type.
Output interface
UART / RS485 / I²C / PWM / analog 0–3.3V — depends on your MCU, distance, and existing firmware.
Operating environment
Temperature range, humidity range, pressure, vibration, expected lifetime — drives BOM & calibration choices.
Volume & timeline
Sample qty, annual quantity, target ship date — gates the pricing tier and customization depth available.
OEM Engineers
Get electrical, mechanical and environmental fit — pinout, protocol, calibration curve, enclosure constraints.
Procurement Teams
Get sample path, MOQ, pricing tiers, lead time and lifecycle commitment for multi-year programs.
Distributors
Get family-level clarity, datasheets and stable SKU continuity for repeatable category positioning.
