Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The SCD40-D-R2 miniature carbon dioxide is a carbon dioxide and relative humidity/temperature (RH/T) sensor that can be mounted into spaces as small as 1 cubic centimetre. These CO2 sensors feature a 2.4V to 5.5V supply voltage range, fully calibrated digital I2C outputs, and ±(30ppm + 3%MV) accuracy nominal. Compared to the SCD30, the SCD40-D-R2 has 1/5 the footprint and measures only 10.1mm x 10.1mm x 6.5mm, and due to the photoacoustic sensing principle, the size of the optical chamber has been significantly reduced without compromising sensor performance.The SCD40-D-R2 features high quality humidity and temperature sensors, and can provide two additional sensor outputs.
