Freescale’s MPL3115A2 employs a MEMS pressure sensor with an I2C interface to provide accurate Pressure/Altitude and Temperature data.
The sensor outputs are digitized by a high resolution 24-bit ADC. It is capable of detecting a change in only 0.05 kPa which equates to a 0.3m change in altitude.
Common applications for the MPL3115A2 include:
personal electronics altimetry,
weather station equipment,
navigation and map assist,
HVAC, etc.
All I2C Mini Modules are designed to operate at 5VDC. Using a convenient 4-Pin plug, devices can be daisy-chained onto the I2C Bus, eliminating the need for soldering. Simply plug together the devices you need for your next automation application.
Pull-up resistors are included with all NCDÂ master devices. If you are wiring in your own I2C port, on-board 4.7K jumper-selectable pull-up resistors are available for convenience purposes.
