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.

BMP280：Bosch’s digital pressure sensor is designed specifically for mobile applications. It features high precision, low power consumption, and a wide measurement range, with a pressure resolution of 0.18 Pa and a measuring range from 300 hPa to 1100 hPa. Its extremely low power consumption makes it suitable for battery-powered devices.

BMP388：Also produced by Bosch, this high-EMC robust sensor is based on mature piezoelectric pressure sensor technology. It is a 24-bit high-precision barometric pressure sensor capable of detecting atmospheric pressure and temperature, and supports I2C/SPI interfaces.

MS5611：Launched by MEAS (Switzerland), it is a new generation of high-resolution barometric pressure sensor with SPI and I²C bus interfaces. It includes a high-linearity pressure sensor and an ultra-low-power 24-bit Σ analog-to-digital converter, providing accurate 24-bit digital pressure and temperature values. The resolution can reach 10 cm. It has characteristics such as low power consumption, high stability, and very low pressure signal hysteresis.

MPL3115A2：NXP’s I²C interface compact piezoresistive absolute pressure sensor, with a pressure range of 20kPa to 110kPa, offers 20-bit pressure measurement, 20-bit altitude measurement, and 12-bit temperature measurement. It features internal full compensation, programmable interrupts, and automatic data acquisition, operating within a temperature range of -40°C to +85°C. It is suitable for automotive electronics and other fields.
