BMP180 for WeMos D1

The BMP180 is a high precision, small volume, low energy consumption of the pressure sensor, and can be used in a mobile device

Its excellent performance, the absolute lowest precision can reach 0.03hPa, and the power consumption is very low, only 3 μ A

BMP180 uses the 8-pin ceramic powerful leadless chip carrier (LCC) ultrathin package through I2C bus, can be directly connected with various microprocessor

Main features:

• Pressure range: 300~1100hPa (elevation 9000 meters ~-500 meters)
• The power supply voltage: 1.8V~3.6V (VDDA), 1.62V~3.6V (VDDD)
• LCC8 package: lead-free ceramics carrier package (LCC)
• Size: 3.6mmx3.8x0.93mm
• Low power consumption: 5 μ A, in the standard model
• High precision: low power mode, the resolution is 0.06hPa (0.5 meters)
• High linear mode, the resolution is 0.03hPa (0.25 meters)
• With the temperature output
• The I2C interface
• Temperature compensation
• Lead-free, meets RoHS specifications
• MSL 1 reaction time: 7.5ms
• The standby current: 0.1 μ A
• No external clock circuit

Typical applications:

• GPS precise navigation (dead reckoning, upper and lower bridge detection etc.)
• Indoor and outdoor navigation
• Leisure, sports and health monitoring
