GMP343 overview
GMP343 is a component documented by Vaisala. The PDF description identifies it as "GMP343 Carbon Dioxide Probe." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.
Datasheet snapshot
- Manufacturer: Vaisala
- Part number: GMP343
- Category: IC
- Datasheet length: 3 Pages
Key features noted in the PDF
- Vaisala CARBOCAP â sensor, a silicon-based non-dispersive infrared (NDIR) sensor
- Single-beam, dual wavelength CO2 measurement with no moving parts
- Compensation options for temperature, pressure, humidity, and oxygen
- Designed for outdoor use Vaisala CARBOCAPâ Carbon Dioxide Probe GMP343 is an accurate and rugged probe-type instrument for ecological measurements. Typical applications include CO.
- Low power consumption and heat emission

Topics covered by the datasheet
The document includes sections related to:
- Features
Engineering review checklist
- Confirm the exact ordering code, package, pinout or terminal arrangement and document revision.
- Compare recommended operating conditions with absolute maximum ratings and retain adequate design margin.
- Validate electrical, thermal, mechanical and environmental behavior in the final application.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
