Product Overview
The MS5837-02BA01 from TE Connectivity is an ultra-compact, high-resolution digital pressure sensor optimized for altimeter and shallow-water depth measurements. Housed in a gel-filled, water-resistant ceramic-metal package, it features a high-linearity piezoresistive element, a low-power 24-bit Delta-Sigma ADC, and factory-calibrated coefficients. The standard I2C interface enables direct communication with most microprocessors, while its low power consumption and 13 cm altitude resolution make it ideal for fitness trackers, smartwatches, dive computers, and underwater drones.
Core Advantages
Water Resistant Gel-Filled Structure
Features an advanced, robust ceramic-metal housing filled with protective silicone gel. This design makes the sensor fully water-resistant and suitable for shallow-water submersions, protecting delicate internal electronics from moisture and harsh humidity arrays.
Ultra-High Resolution Tracking
Equipped with an onboard 24-bit Delta-Sigma analog-to-digital converter, providing extreme computational resolution capable of detecting minute altitude changes down to 13 cm in open air or fractions of a millimeter underwater.
Simplified I2C Digital Connectivity
Integrates a standard I2C interface bus that streams fully calibrated digital pressure and temperature outputs, eliminating the need for external signal conditioning components or complex analog-to-digital conversion circuits.
Optimized Low-Power Profile
Engineered with adaptive power management and fast conversion modes that reduce active current draw to as little as 0.6 μA, making it a stellar solution for battery-powered wearable devices and portable IoT hardware platforms.

Frequently Asked Questions
Q1: Is your current stock inventory of the MS5837-02BA01 completely original and new?
A: Yes, we guarantee that all MS5837-02BA01 pressure sensors in our stock are 100% brand-new, authentic factory products from TE Connectivity, strictly maintained under anti-static moisture-sealed tray conditions.
Q2: What is the maximum water depth that this specific model can measure safely?
A: The MS5837-02BA01 is rated up to a maximum pressure limit of 2000 mbar (2 bar), which equates to a maximum depth of approximately 10 meters (33 feet) in water, making it perfect for swimming tracking and shallow submersions.
Q3: How does the protective gel layer affect reflow soldering or cleaning during PCB assembly?
A: The MS5837-02BA01 is designed for standard SMT reflow soldering processes. However, to prevent contamination or damage to the internal gel matrix, the sensor must never be exposed to ultrasonic cleaning wash systems or high-pressure air streams.
Q4: How can our engineering desk request specific driver source codes or calibration math sheets for this part?
A: Please complete our Quick Inquiry web form on this page with details about your processing parameters. Our application support desk will process your inquiry and dispatch the available technical documentation package within 24 hours.
