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.
