BMP180 Pinout Equivalent

1：Overview of the BMP180：

BMP180 is a high-precision Digital pressure sensor produced by Bosch. It has a power consumption of 5μA in standard mode and 0.1μA in standby mode. It features an integrated 176-bit E²PROM that stores 11 calibration parameters. Temperature drift and linear error compensation are required through software to enhance measurement stability. It supports temperature compensation algorithms to improve measurement accuracy. Common applications include GPS dead reckoning, indoor/outdoor positioning, and drone altitude control.

2：BMP180 Important pin function definition:

Pin Number	Pin Name	Description
Pin1	VCC	Power pin, connect to a 3.3V DC power supply to power the sensor.
Pin2	GND	Ground pin, connected to the ground of the power supply, provides a reference potential for the circuit.
Pin3	SDA	The serial data pin is used for data transmission in I²C communication and can be connected to the data pin of a microcontroller or another master device.
Pin4	SCL	The serial clock pin provides the clock signal for I²C communication, ensuring synchronization for data transmission.
Pin5	3.3V	This pin is available only in the 5-pin module. When there is no 5V power supply, you can connect a 3.3V power supply to this pin to power the module.

3：Alternative model recommendation
