描述

The T6613-C is a small, compact CO2 sensor module designed for integration into OEM equipment and existing controls, featuring non-dispersive infrared (NDIR) detection with gold-plated optics and diffusion sampling with gas ports. The module measures carbon dioxide concentrations from 0 to 2000 ppm with accuracy of ±30 ppm or 3% of reading (400–1250 ppm range) and ±5% of reading plus 30 ppm (1250–2000 ppm range), and includes Telaire's patented ABC Logic self-calibration algorithm that eliminates the need for recalibration in most applications. Operating over a temperature range of 0°C to 50°C with a response time under 2 minutes and signal updates every 4 seconds, the module provides both digital (UART at 19200 baud and I2C up to 100 kHz) and analog (0 to 4 VDC) outputs, powered by a regulated 5 VDC supply consuming 0.90 watts peak and 0.165 watts average. The T6613-C is ideal for HVAC systems, indoor air quality monitoring, and building automation applications where reliable, factory-calibrated CO2 measurement is required without ongoing maintenance.
