The electronic design is based on MS5837-30BA pressure sensor which is a high-resolution pressure and temperature sensor from TE Connectivity with I2C bus interface. This sensor is optimized for water depth measurement systems with a resolution of 0.2 cm. 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.
Small dimensions of only 9 mm allow integration of the pressure sensor pcb in so many underwater related applications. This sensor module generation is based on leading MEMS technology from TE proven experience and know-how in high volume manufacturing of sensors modules.
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.
