SCD40-D-R1
by Sensirion(瑞士盛思锐)Indoor air-quality monitors and ventilation controllers use carbon dioxide measurements to track occupied spaces. Sensirion's SCD40-D-R1 is a CO₂ sensor from a family that also measures temperature and humidity, bringing these environmental readings into an embedded design. The supplied surface-mount footprint is LGA-20_L10.1-W10.1-P1.25-TL, with 21 pads, and the corresponding schematic symbol contains 21 pins. A 3D model accompanies the free KiCad files for visualizing placement within the board assembly. This library came from a real ProtoFlow import, converted and checked in the editor. Open SCD40-D-R1 directly in ProtoFlow to place the sensor in your design.
