Barometric Pressure Unit is a barometer unit, which integrates the Bosch BMP280 pressure sensor to measure atmospheric pressure and estimate the altitude. The relative accuracy can reach ± 0.12hpa, equivalent to ± 1m height difference. At the same time, the temperature drift coefficient is very low, which can reach 1.5 PA / K, that is, the temperature drift is 12.6 cm / K. in addition, there is an integrated temperature sensor in the chip.Product Features * Air pressure sensor, with temperature sensor on chip, can be measure simultaneously * The accuracy is ± 0.12hpa * Temperature drift coefficiency 1.5pa/k * Supports periodic measurement * Integrated 5-segment filter * Support low power consumption * Development platform: Arduino, UIFlow (Blockly, Python) * 2x LEGO™ compatible holes Include * 1x Barometric Pressure Unit * 1x Grove Cable (5cm) Application * height detector * Weather station Specification Resources Parameter Air pressure measurement range 300 - 1100 hPa(+9000m ~ -500m) Relative accuracy 0.12hPa Absolute accuracy 1hPa Temperature measurement range -40 ~ +85°C Temperature resolution 0.01°C Pressure resolution 0.16Pa Temperature coefficient offset 1.5 Pa/K(12.6 cm/K) Current consumption 2.7μA @ 1 Hz sampling rate Voltage 1.71V - 3.6V Communication protocol I2C：0x76 Net Weight 8g Gross Weight 21g Produce Size 24*24*13mm Package Size 35*36*18mm LEARN AND DOCUMENTS * DOCUMENTS https://elecena.pl/product/22723875/m5stack-barometric-pressure-unit-bmp280-discontinued 2023-03-07 https://elecena.pl/product/22723875/m5stack-barometric-pressure-unit-bmp280-discontinued 2024-09-19
