Sensirion SCD4x Miniaturized CO2 Sensors
SCD4x Miniaturized CO2 Sensors
Sensirion SCD4x Miniaturized CO2 Sensors are CO2 and RH/T sensors that fit in a space of just one cubic centimeter. 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 miniaturized by a factor of 5, resulting in dimensions of just 10.1mm x 10.1mm x 6.5mm. With the use of the photoacoustic sensing principle, the dimensions of the optical cavity are greatly reduced without compromising on sensor performance. 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.
