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
sensor with low power (0.6µA), 24-bit digital output (I
2
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 (±2ºC) 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.)
Our MS5837-02BA provides exceptional performance, reliability
and accurate performance from a brand you can trust.
