MS5837-02BA Gel-filled, ultra-compact, water resistant digital pressure and temperature sensor Take your devices to the next level with our MS5837-02BA pressure and temperature sensor module. This ultra-compact (3.3 x 3.3 x 2.75 mm), gel-filled sensor is optimized for consumer devices such as fitness trackers, drones and wearables, providing a robust sensor package to withstand the harsh environments often encountered in these applications. Expanding on TE Connectivity s (TE) MS5837 series of ultra- compact, digital altimeters, our 2 bar models offers options for shielding and high chemical endurance. This MEMS based sensor includes a high-linearity pressure 2 sensor with low power (0.6A), 24-bit digital output (I C) and an altitude resolution at sea level of 13 cm. This enables high resolution measurements such as counting flights of stairs. The board level design delivers sensing accuracy for both pressure (0.5mbar) and temperature (2C) measurements. Lid shield option reduces signal noise and interference that may be experienced with sensors installed in plastic housings or high electrical noise environments with integrated shielding. (Non-shielded models should only be recommended for use in applications with metal housings.) APPLICATIONS Our MS5837-02BA provides exceptional performance, reliability Fitness Trackers and accurate performance from a brand you can trust.
