Occupying just 1 cm³ , the SCD40 sensor from Sensirion performs accurate carbon dioxide (CO₂ ), relative humidity, and temperature monitoring. The sensor’s dimensions of 12×12×7 mm make it five times smaller than its predecessor, the SCD30. According to the Swiss manufacturer, photoacoustic sensing allows the dimensions of the SCD40’s optical cavity to be reduced without compromising sensor performance.

Sensirion will introduce the SCD40 CO₂ , relative humidity, and temperature sensor at this year’s Sensor+Test 2019 in Nuremberg (June 25-27) and Sensors Expo 2019 in San Jose (June 26-27). The manufacturer reports that the price-performance ratio of the SCD40 is particularly well-suited for high-volume and cost-sensitive applications, including IoT, automotive, HVAC, appliances, and consumer goods.

A datasheet for the SCD40 sensor was not available at the time of this announcement. For more information about Sensirion’s complete line of environmental sensors, click here.
