Automotive CO2 sensor monitors human and pet occupation of parked vehicles

Mouser now stocks the T6743-40K-E Automotive CO2 Sensor from Amphenol Advanced Sensors. The device is an NDIR CO2 sensor that implements a single-channel diffusion sampling method for automotive HVAC applications, including automatic fresh air control and safety sensing for CO2 refrigerants. The CO2 sensor can also supply an important safety feature by monitoring parked vehicles and triggering an alarm if human or pet occupation is detected.

The sensor can detect in-cabin CO2 levels to stop driver drowsiness. The device can also be utilised to decrease variations in heating and cooling in-cabin through demand control ventilation (DCV). Employing this CO2-based ventilation control, the air is continually monitored, and the influx of outside air is taken into account, eradicating the air conditioning system's need to bring air in mechanically.

The automotive sensor supplies an operating temperature range of -40C to +90C. Each sensor is factory-calibrated to measure CO2 levels up to 5,000ppm. The sensors offer a 5s sample rate in active mode and a 15s sample rate in low-power mode. Together with the patented ABC Logic lifetime calibration warranty, its low power consumption, compact design, and simple product integration make the sensor an ideal gas-sensing solution.
