AJMRTC 5Pcs BMP280 Digital Barometric Pressure Sensor Module, 3.3V High Precision Atmospheric Pressure Temperature Sensor, I2C SPI Interface, Upgrade Replacement for BMP180 BMP085 for Arduino, STM32

AJMRTC BMP280 pressure sensor module is a common upgrade for traditional BMP180 atmospheric sensors. It can collect ambient atmospheric pressure and temperature at the same time, and calculate relative altitude after program calibration using sea-level pressure reference value. It supports I2C and SPI two communication protocols, works seamlessly with Arduino, STM32, ESP32 and Raspberry Pi. Multiple oversampling settings are available to balance measurement accuracy and power consumption for different scenarios. It is widely used for DIY weather stations, model aircraft altitude holding, environmental monitoring instruments and indoor and outdoor pressure logging. Note that altitude calculation is affected by local real-time atmospheric pressure; regular calibration is required to reduce deviation. Keep the module away from direct water vapor, strong wind and condensation to avoid unstable measurement results. This listing contains five sensor modules for multi-point monitoring layout or spare use.
