Product description
LPS25 air pressure sensor with SPI and I2C. High resolution and fast refresh rate. An interrupt output can be activated at programmable threshold values. Useful for weather measurement (high or low pressure) or as an altimeter in drones. I2C with Qwiic for simple wiring, with optional SPI for I2C address conflicts.
Qwiic connectors for smooth, solder-free connection of voltage and I2C with a cable. Two connectors - can be connected in series with other Qwiic devices.
Power, SPI, interrupt and I2C are alla available on a 2.54mm pitch connector for use with breadboard or prototyping boards. A pin header for this is included (not mounted).
Compatible with Raspberry Pi and Arduino. Code examples, documentation and libraries are available at Adafruit.
