Product Introduction
1. Description of US MEAS Digital Pressure and Altitude Sensor MS5637-30BA:
Digital pressure and altitude sensorMS5637-30BA is optimized for barometric pressure measurement systems with a resolution of 0.5 mbar. The sensor module contains a highly linear pressure sensor and an ultra-low-power 24-bit ΔΣ ADC with internal factory calibration coefficients. It provides precise 24-bit digital pressure and temperature values and various operating modes, allowing users to configure conversion speed and power consumption as needed. The high-resolution temperature output enables the pressure measurement system and thermometer functions without additional sensors. MS5637-30BA can interface with almost any microcontroller. The communication protocol is simple, requiring no programming of internal registers. The gel protection and anti-magnetic stainless steel cap protect the pressure chip. This new sensor module is based on advanced MEMS technology and benefits from MEAS Switzerland's extensive experience and expertise in R&D and mass production of pressure sensor modules over the past decade.
