CO2/RH/T Sensor Breaks The Size Barrier


Sensirion’s SCD40 is described as the first miniaturized CO2 and RH/T sensor that fits in a space of just one cubic centimeter. The component is based on the photoacoustic sensing principle and combines minimal size with maximum performance to open numerous integration and application possibilities. According to its maker, the sensor’s price-performance ratio makes it desirable for high-volume and cost-sensitive applications.

The SCD40 measures 12 mm x 12 mm x 7 mm3, a footprint that has been miniaturized by a factor of 5 compared to its predecessor, the SCD30. Using the photoacoustic sensing principle, the dimensions of the optical cavity are reduced without compromising on sensor performance. For further information, visit Sensirion.
