MS5837-02BA
Ultra-small Gel Filled
Pressure & Temperature Sensor,
with Stainless Steel Cap
Take your devices to the next level with our MS5837-02BA pressure
sensor module. This ultra-small gel filled pressure sensor is optimized
for both altimeter and barometer applications.
Optimized for consumer devices such as wearables, multisport
watches and fitness trackers the MS5837-02BA’s robust sensor
package enables it to withstand harsh environments often encountered
in these applications.
This MEMS based sensor includes a high-linearity pressure sensor
with an ultra-low power 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.
This ultra-compact micro altimeter allows for design flexibility and is
one of the smallest gel filled watertight sensor in the market. The robust
sensor package consists of ceramic and metal materials. A high-
resolution temperature output allows the implementation of a
thermometer ion without any additional sensor.
Expanding on TE Connectivity's (TE) MS5837 series of ultra-compact
digital altimeters, our new generation 2 bar models offer options for
improved endurance in chlorine environments and shielding for
reduced signal noise and interference. This new generation of sensor
modules was developed by TE with leading MEMS technology and our
proven experience in design and manufacturing of altimeter modules.
