Ultra-small, gel-filled, pressure sensor with stainless steel cap

The MS5837-30BA is a high-resolution pressure and temperature sensor from TE Connectivity (TE) with I2C bus interface. This sensor is optimized for water depth measurement systems with a resolution of 0.2 cm. The sensor module includes a high linearity pressure sensor and an ultra-low power 24-bit delta sigma ADC with internal factory calibrated coefficients. It provides a precise digital 24-bit pressure and temperature value and different operation modes that allow the user to optimize for conversion speed and current consumption. A high-resolution temperature output allows the implementation in depth measurement systems and thermometer function without any additional sensor. The MS5807-30BA can be interfaced to virtually any microcontroller. The communication protocol is simple, without the need of programming internal registers in the device. The gel protection and antimagnetic stainless-steel cap make the module water resistant.

Small dimensions of only 3.3 x 3.3 x 2.75 mm allow integration in mobile devices. Enhanced construction and design materials allow for enhanced chemical endurance in applications with harsh liquid media environments with limited exposure. This sensor module generation is based on leading MEMS technology from TE proven experience and know-how in high volume manufacturing of sensors modules.
