The BMP581 delivers next-gen\nperformance – ideal for environmental measurements, wearables or stable\naltitudes for copters. Extremely precise: relative accuracy ±0.4Pa (≈±3.3cm)\nat 900-1100hPa, 25°C; noise up to 1cm (0.08Pa) Absolute accuracy: type. ±30 Pa\n(≈ 2.5 m). I2C and SPI: choose simple wiring via I2C or collision-free\nmultiple sensors via SPI Easy integration: 3.3V regulator \u0026amp; level shifting -\ncompatible with 3V\/5V logic STEMMA QT\/Qwiic: two connectors for solderless\nconnections and daisy chain (cable separately). Temperature: ± 0.5 °C.\nCompatible: firmware\/software compatible with BMP580. Ready to go: Arduino\nlibrary available Perfect for: precise altimetry, weather stations, indoor\nnavigation, drones, sports and altitude tracking. Note: For absolute altitude,\nyou need to calibrate the local air pressure at sea level - this applies to\nall pressure-based altimeters.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003ePrecision  Ultra-high accuracy: relative accuracy  0.4 Pa (approx. 3.3 cm height) and very low noise up to 0.08 Pa (1 cm) - ideal if you want to measure fine height differences; temperature measurement 0.5 C.\u003c\/li\u003e\n         \u003cli\u003eCONNECTIVITY - I2C or SPI: Use I2C for fast, easy cabling or SPI if you want to operate multiple sensors without I2C address conflicts.\u003c\/li\u003e\n         \u003cli\u003ePLUG-\u0026amp;PLAY - Pre-assembled breakout with 3.3V controller and level shifters: runs smoothly on 3.3V and 5V microcontrollers; STEMMA QT (Qwiic compatible) for solderless connections.\u003c\/li\u003e\n         \u003cli\u003eFlexible use  perfect for drones, wearables or environmental measurements: great as a precise altimeter; for absolute sea level, you must take into account the current reference pressure as with all barometers.\u003c\/li\u003e\n         \u003cli\u003eEASY INTEGRATION - Next Gen sensor, firmware-compatible with previous BMP models and Arduino library available - get started in minutes.\u003c\/li\u003e\n  \u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"BMP581","offer_id":44374940942516,"sku":"de-B0FXGGGM7Q","price":161.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9906\/1172\/files\/de-B0FXGGGM7Q.jpg?v=1788269088","url":"https:\/\/auspowers.com\/products\/adafruit-bmp581-i2c-spi-temperature-and-air-pressure-sensor-stemma-qt-6407","provider":"AusPower Australia","version":"1.0","type":"link"}
