{"title":"LPS331AP Pressure/Altitude Sensor Carrier with Voltage Regulator","handle":"lps331ap-pressure-altitude-sensor-carrier-with-voltage-regulator","url":"/products/lps331ap-pressure-altitude-sensor-carrier-with-voltage-regulator","description":"A breakout board for ST's LPS331AP digital barometric pressure sensor. This sensor measures absolute pressure from 260 to 1260 mbar with excellent accuracy (±2 mbar), making it ideal for altitude estimation, weather monitoring, and indoor navigation applications.\n\nThe board includes an onboard 3.3V regulator and level shifters, allowing it to work with both 3.3V and 5V systems. Standard 0.1\" pin spacing makes it breadboard-friendly.\n\nKey Features\n\n\nHigh Accuracy – ±2 mbar absolute accuracy over temperature\n\nLow Noise – 0.02 mbar RMS in high-resolution mode\n\nWide Range – Measures 260 to 1260 mbar\n\nDual Interface – Supports both I²C and SPI\n\nVoltage Flexible – Works with 2.5V to 5.5V input\n\nBreadboard Friendly – 0.1\" (2.54mm) pin spacing\n\n\nIdeal For\n\nAltitude measurement for drones and rockets\nWeather station projects\nIndoor floor-level detection\nBarometric data logging\nGPS altitude augmentation\n\n\nSpecifications\n\n\nSensor: ST LPS331AP\n\nPressure Range: 260–1260 mbar (26–126 kPa)\n\nAbsolute Accuracy: ±2 mbar\n\nRMS Noise: 0.02 mbar (high-resolution mode)\n\nInterface: I²C or SPI\n\nInput Voltage: 2.5V to 5.5V\n\nOnboard Regulator: 3.3V\n\nPin Spacing: 0.1\" (2.54mm)\n\n\nPackage Contents\n\n1× LPS331AP Pressure Sensor Breakout Board\n\n\n\nTip: Pressure readings can be converted to altitude using the barometric formula. At sea level, expect readings around 1013 mbar.\n","vendor":"Pololu","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":14698,"title":"Default Title","sku":"PL-2126","price":10.2,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":5,"option1":"Default Title"}]}
