SE-0029

The K-22 OC (Open Collector) CO2 sensor module is designed to be built into stationary ventilation equipment (such as window vent or duct exhaust actuators) and to transmit CO2 levels in real-time.

This sensor provides a 100ma current sink to drive external loads such as relays or indicators. The open collector activates at 1,000 ppm and remains activated until the CO2 level declines to less than 800 ppm, making the K-22 OC the ideal component for a simple control system.

Based on reliable infrared gas sensing technology (NDIR), the K-22 is the best value sensor available for cost-sensitive products on the market today. Contact us directly for wholesale pricing on large quantities.

Communications
In addition the K-22 OC supports the I2C protocol. An I2C to USB cable is available here to make it easy to read the sensor.
