Gas sensors

Introducing technical information useful for design and evaluation using Senseair sensor modules.

When integrating a sensor module into equipment, various design requirements need to be considered, including power supply design, communication method, mounting size, measurement interval, and software integration. This page introduces design support information for a wireless CO₂ sensor beacon using a Senseair sensor module. You can find information useful for developing portable IAQ monitors and wireless air quality sensing devices, such as long battery operation with a coin cell, wireless transmission via Bluetooth® Low Energy, and a compact module configuration.

For customers who want to design at the component level

If you want to design a custom NDIR gas sensor at the component level rather than using a ready-to-use module, please see AKM gas sensor components. This section introduces key devices required for gas sensor design, including infrared LEDs, infrared photodiodes, and AFE ICs.
