Digital Barometric Pressure Sensor Module

The WS5607 is an integrated barometric pressure module that combines a silicon piezoresistive pressure sensor with a 24-bit ADC (analog-to-digital converter). This module features a compact size (5.0*3.0*1.2mm), high accuracy, a wide temperature range, low power consumption, and excellent stability. It operates within a broad voltage supply range from 2.3V to 5.5V and includes an internal clock, making it more convenient for customers in product design.

The product offers two communication interfaces: SPI and I2C. The capacitive pressure sensor overcomes the significant pressure errors caused by temperature variations in piezoresistive pressure sensors during pressure measurement. In addition to measuring pressure, the WS5607 can also function as a standalone temperature sensor. Based on the relationship between atmospheric pressure and altitude, the product can be used for measuring both altitude and relative height.
