Waveshare BMP390 Barometric Pressure Sensor Module Accurate Altitude, Temperature Sensor and Pressure Measurement for IoT, Drones, and Weather Monitoring

 Description:

The Waveshare BMP390 High Precision Barometric Pressure Sensor is a compact and highly accurate sensor module designed for precise measurement of barometric pressure, altitude, and temperature. Powered by Bosch’s advanced BMP390 chip, this sensor delivers exceptional performance with ultra-low noise and high resolution—measuring pressure with up to 0.01 hPa, altitude with 0.1-meter precision, and temperature with 0.01°C accuracy.

Ideal for weather monitoring, environmental sensing, drone altitude control, GPS enhancement, and IoT-based applications, the BMP390 sensor is known for its stability, reliability, and low power consumption. Its compact form factor and versatile I2C/SPI interface make it easy to integrate with platforms like Arduino, Raspberry Pi, ESP32, and other microcontrollers.

Whether you're developing an altimeter, building a weather station, or creating high-precision IoT devices, the Waveshare BMP390 sensor is a perfect fit for applications requiring accurate environmental data.
