SCD4x Miniaturized CO2 Sensors

Sensirion SCD4x Miniaturised CO2 Sensors are CO2 and RH/T sensors that fit within a space of just one cubic centimetre. These CO2 sensors offer a 2.4V to 5.5V supply voltage range, fully calibrated digital I2C output, and ±(30ppm + 3%MV) accuracy rating. Compared to the SCD30, the SCD4x footprint has been miniaturised by a factor of 5, resulting in dimensions of just 10.1mm x 10.1mm x 6.5mm. With the use of the photoacoustic NDIR sensing principle, the dimensions of the optical cavity are greatly reduced, without compromising sensor performance. CO2 sensor compliant with RESET, WELL, Title 24, ASHRAE 62.1 building standards. The SCD4x series features a quality humidity and temperature sensor that delivers two additional sensor outputs. Sensirion SCD4x miniaturized CO2 sensors are ideal for sensing markets such as IoT, automotive, HVAC, appliances and consumer goods.
