Product specifications
The CAPB18-002 is an integrated environmental sensor unit with an ultra-small size. The unit combines digital high accuracy pressure sensor and high SNR analog microphone.
The pressure module highlights a capacitive sensing element, 24-bit results and FIFO output, which bring in high accuracy, ultra high precision during temperature changes and very low power consumption. Its I2C interface allows for easy system integration with microcontroller.
The microphone module features high sensitivity and high SNR with low power consumption. The analog output can trace change of environment sound signal timely.
