1. Product Overview
The DP series water depth sensor adopts TE's MS5837 pressure sensor, which is a new generation of high-resolution I2C interface pressure sensor. The MS5837 pressure sensor is a high-precision water depth measurement Ideal for water depth measurement with a resolution of up to 2mm. The MS5837 pressure sensor module includes a high linearity pressure sensing element and an ultra-low power consumption 24-bit ΔADC with built-in factory calibration coefficients. The MS5837-30BA pressure sensor provides highly accurate 24-bit pressure and temperature digital outputs with configurable conversion speed and power consumption based on application needs. The high-resolution temperature output can simultaneously realize the function of a thermometer. The MS5837-30BA pressure sensor can cooperate with all forms of microcontrollers. The communication protocol is very simple and there is no need to modify the internal registers.
2. Performance parameters
(Note: The I2C logic level is 3.3V. Pay attention to whether the output voltage of the I2C port of the microcontroller is 3.3V. If it is 5V, a voltage conversion chip needs to be connected)
3. Pin Instructions
(Note: Some sensor signal lines may not be in these four colors, and the corresponding functions are also different. Please check the manual.)
4. Working principle< /span>
The MS5837-30BA pressure sensor module is an ultra-small rubber-filled pressure sensor optimized for altimeter and barometer applications. MEMS-based sensors include a high linearity pressure sensing and temperature sensor with ultra-low power 24-bit digital output (I2C) and water depth measurement resolution of up to 2mm and altitude resolution of 13cm. Temperature and pressure calibration and calibration are shipped from the factory.
