MS5637 PERIPHERAL MODULE Digital Pressure Sensor General Description The MS5637 peripheral module provides the necessary hardware to interface the MS5637 digital barometric pressure and temperature sensor to any system that utilizes Pmod compatible expansion ports configurable for I2C communication. The MS5637 sensor is a self-contained pressure and temperature sensor that is fully calibrated during manufacture. The sensor can operate from 1.5V to 3.6V. The sensor module includes a high-linearity pressure sensor and an ultra-low power 24 bit _Σ ADC with internal factory-calibrated coefficients. Specifications Measures pressure from 300mbar to 1200mbar Measures temperature from -40°C to 125°C I2C communication Fully calibrated Fast response time Very low power consumption Features 12-pin Pmod compatible connector I2C interface Secondary 12-pin connector allows daisy chain FPGA fabric available for download µC C code available for download 24 bit resolution for pressure 24 bit resolution for temperature Parameters stored on chip MS5637 PERIPHERAL MODULE Digital Pressure Sensor Performance 300 to 1200mbar pressure range -40°C to 85°C temperature range Very low power consumption Operates from 1.5V to 3.6V Altitude resolution at sea level is 20 cm of air Fast conversion time – 0.5 mS typical Schematic SENSOR SOLUTIONS /// MS5637 PERIPHERAL MODULE Page 2 MS5637 PERIPHERAL MODULE Digital Pressure Sensor Connector Pin Assignments (12C Communications) System Plug (Table 1) Expansion Socket (Table 2) Connector J1 Pin No. 1 2 3 4 5 6 7 8 9 10 11 12 Signal N/C N/C SCL SDA GND Vdd N/C N/C SCL SDA GND Vdd Connector J2 Description Not Connected Not Connected I2C Serial Clock I2C Serial Data Ground Power Supply Not Connected Not Connected I2C Serial Clock I2C Serial Data Ground Power Supply Pin No. 1 2 3 4 5 6 7 8 9 10 11 12 Signal N/C N/C SCL SDA GND Vdd N/C N/C N/C N/C N/C N/C Description Not Connected Not Connected I2C Serial Clock I2C Serial Data Ground Power Supply Not Connected Not Connected Not Connected Not Connected Not Connected Not Connected Dimensions(mm) SENSOR SOLUTIONS /// MS5637 PERIPHERAL MODULE Page 3 MS5637 PERIPHERAL MODULE Digital Pressure Sensor Detailed Description I2C Interface The peripheral module can interface to the host in one of two ways. It can plug directly into a Pmod-compatible port (configured for I2C) through connector J1, or in this case, other I2C boards can attach to the same I2C bus through connector J2. I2C Interface (Daisy Chaining Modules) Alternatively, the peripheral module can connect to other I 2C-based Pmod modules through the expansion J2 connector. Connector J1 provides connection of the module to the Pmod host. The pin assignments and functions adhere to the Pmod standard as shown in Table 1. The J2 connector allows the module to be connected through a daisy-chain from another I2C module and/or provide I2C and power connections to other I2C modules on the same bus. See Table 2. External Control Signals The IC operates as an I2C slave using the standard 2 wire I2C connection scheme. The IC is controlled either by the host (through the Pmod connector). In cases where one or more of the SCL and SDA signals are driven from an external source, resistors R1, R2 provide pull-up. However, this also increases the apparent load to the external driving source. If the external source is incapable of driving these loads, they should be removed.
