Introduction

CAPB18-002 is an ultra-compact integrated environmental sensor unit combining a digital high-precision pressure sensor and a high-SNR analog microphone.

The pressure module employs a capacitive sensing element with 24-bit output and FIFO output capability, featuring high accuracy, exceptional precision over temperature variations, and ultra-low power consumption. Its I2C interface simplifies system integration with microcontrollers.

The microphone module offers high sensitivity, high SNR, and low power consumption. The analog output tracks ambient acoustic signals in real time.
