Product description: BMP388 - precision pressure and altitude sensor - I2C / SPI - Waveshare 16115
The module is based on a precise BMP388 pressure sensor from Bosch, allowing measurement of relative height. It is used in IoT projects, monitoring environmental parameters, drones and navigation. It has a wide measurement range from 300 hPa to 1250 hPa . The relative pressure accuracy is up to ±0.08 hPa in the range from 900 hPa to 1100 hPa, at temperatures from 25°C to 40°C. Additionally, the sensor allows you to measure the ambient temperature with an accuracy of ±0.5°C. This allows compensation for the characteristics of the barometric sensor. Communication takes place via the I2C or SPI interface. Supply voltages range from 3.3 V to 5 V, which facilitates communication with microcontrollers such as Arduino .
