Sensirion SCD42-D-R2, Carbon Dioxide Gas Sensor IC for CO Detectors

The SCD42 is Sensirion’s miniature CO2 sensor that uses smart ventilation systems to regulate ventilation in the most energy-efficient way. This sensor is developed on the photoacoustic sensing principle and Sensirion’s patented PAsens® and CMOSens® technology. This offers high accuracy available in the small form factor of 10.1 x 10.1 x 6.5 mm3. The CO2 SMD assembly allows cost-effective and space-saving integration of the sensor. On-chip signal compensation is achieved with the built-in SHT4x humidity and temperature sensor. SCD42 can help you maintain a low CO2 concentration allowing a healthy, productive environment.

The SEK-SCD41-Sensor Evaluation kit, is also available see RS 215-1862 which includes 1 x SCD41 development board, 1 x RJ45 adapter cable, 1 x Jumper wire set.
SensorBridge is available separately see 195-0680
