VCC is 5V. The output high level 3.3V can be powered by 5v. There is a voltage conversion chip inside, but only one power supply mode can be selected for 5v and 3.3v. If you select 3.3v, you can no longer use 5v. If you select 5v, you can no longer use it. 3.3v

 

 BMP180 is a pressure sensor with high precision, small size and low energy consumption, which can be used in mobile devices

 

Its performance is excellent, the absolute accuracy can reach as low as 0.03hPa, and the electrode consumption is low, only 3μA

 

BMP180 uses a powerful 8-pin ceramic leadless chip carrier (LCC) ultra-thin package, which can be directly connected to various microprocessors through the I2C bus
