Fermion: BMP388 Digital Pressure Sensor

SKU: SEN0371

The BMP388 Pressure and Temperature Sensor is DFRobot's advanced breakout sensor for precise pressure, temperature, and altitude measurements, ideal for drones. It supports Arduino with lower power consumption and higher resolution than its predecessors, BMP180 and BMP280. Utilizing Bosch’s piezo-resistive technology, the sensor provides high accuracy (±8Pa for pressure and ±0.5℃ for temperature) and excellent EMC robustness. Its compact size makes it suitable for various applications, including drones, where precise altitude and floor height measurements are crucial. Note: Handle the sensor with care to avoid damaging its sensitive components.
