Description
- Pololu LPS22DF Digital Barometer Sensor w/ Integrated Voltage Regulator
- High-precision pressure sensing
- Altitude conversion capable
- Dual I²C/SPI communication
- Embedded temperature compensation
- User-friendly design for easy integration
The Pololu LPS22DF Digital Barometer Sensor w/ Voltage Regulator is designed to measure atmospheric pressures ranging from 260 mbar to 1260 mbar with a high degree of accuracy, achieving absolute accuracy down to ±0.5 mbar. It is capable of converting pressure measurements to altitudes, making it suitable for a variety of applications. The sensor is equipped with both I²C/I3C and SPI interfaces for communication.
This compact carrier board for the ST LPS22DF MEMS absolute pressure sensor is designed to facilitate the use of the sensor for students and hobbyists. It includes a 3 V linear regulator and level shifters to accommodate a wide input voltage range, ensuring compatibility with various microcontroller voltages. The board comes fully populated with surface-mounted components, including the LPS22DF sensor itself.
Please note that it is recommended to thoroughly review the LPS22DF datasheet before using this product. The sensor operates at voltages below 3.6 V, which may require special consideration when interfacing with microcontrollers operating at higher voltages.
- 1x Pololu LPS22DF Digital Barometer Sensor w/ Voltage Regulator
- 1x 1x8 strip of 0.1-inch header pins
