Item Code: MD037

The atmospheric pressure measurement module is based on the BMP-280 sensor from BOSCH. This sensor is an improved version of the BMP180 and features a smaller size, lower power consumption, high operating accuracy, precise factory calibration, and two serial interfaces: I2C and SPI.

Specifications:

• Supply voltage: from 1.71 V to 3.6 V
• Max I2C interface speed: 3.4 MHz
• Current consumption: 2.7 µA at a sampling frequency of 1 Hz
• Interface: I2C, SPI (4 Wires), SPI (3 Wires)
• Calibration: factory
• Noise level: up to 0.2 Pa (1.7 cm) and 0.01 temperature
• Pressure measurement range: from 300hPa to 1100hPa (9000 m to -500 m)
