STCC4-D-R3
Overview
The STCC4-D-R3 is a miniature CO2 sensor from Sensirion based on a thermal conductivity measurement principle. It provides carbon dioxide concentration readings over I2C in an extremely compact LGA package, making it suitable for high-volume integration where space is at a premium. Unlike traditional NDIR sensors, this thermal conductivity approach allows for a much lower profile and a reduced bill of materials.
Why Choose This Part
The STCC4-D-R3 stands out for its ultra-low profile and small 3x4mm footprint, which is significantly smaller than traditional optical CO2 sensors. It features a low continuous measurement current of 950uA and a deep sleep mode of 1uA, enabling battery-powered operation in portable environmental monitors.
Applications
Key Specifications
Getting Started
Engineers should integrate the sensor via the I2C interface, ensuring the VDD supply remains within the 2.7V to 5.5V range. Since it is reflow solderable in a standard LGA-8 package, it can be treated like a standard SMD component, though care should be taken to follow Sensirion's handling instructions regarding the sensor opening. Implementation typically involves using Sensirion's driver libraries to handle the thermal conductivity compensation algorithms.
