Gel-filled, ultra-compact, water resistant digital pressure and temperature sensor.

Optimized for consumer devices such as fitness trackers, drones and wearables 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 (I2C) 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 water resistant sensors in the market. The robust sensor package consists of ceramic and metal materials. The board level design delivers sensing accuracy for both pressure (±0.5mbar) and temperature (±2ºC) measurements. Expanding on TE Connectivity's (TE) MS5837 series of ultra-compact digital altimeters, this 2 bar models offer options for improved endurance in media environments and integrated  shielding for reduced signal noise and interference. Our MS5837-02BA provides exceptional performance, reliability and accurate performance from a brand you can trust.
