BMP180 sensor(dual-hole)

Description

Main specifications / special functions:
VCC is 5V, the output high level 3.3V, which can be powered by 5V, there are voltage conversion chips, but 5V and 3.3V can only choose one power supply mode. If you choose 3.3V3.3V
BMP180 is a high-precision, small-volume, consumption of pressure sensor, which can be applied to mobile devices
Its performance, accuracy of 0.03HPa, and low power consumption, only 3μA
The BMP180 uses a powerful 8-PIN ceramic-free chip bearing (LCC) packaging, which can be directly connected to various microprocessors through the I2C bus

main feature:

Pressure range: 300 ~ 1100HPA (9000 meters above sea level ~ -500 meters)
Power voltage: 1.8V ~ 3.6V (VDDA), 1.62V ~ 3.6V (DVD)
LCC8 packaging: lead-free ceramic carrier packaging (LCC)
Size: 3.6mmx3.8×0.93mm
Low power consumption: 5μA, in the standard mode
High-precision: In low power consumption mode, the resolution is 0.06HPa (0.5 meters)
