Barometric Pressure Sensor MEMs - SCP1000-D01

sku: COM-08128

Description: This is the very first absolute pressure sensor on the market to use MEMs technology to grant 17-bit resolution. Under ideal conditions, this sensor can detect the pressure difference within a 9cm column of air. Breakout board available below!

Please note: We now stock the ASCI rev C (IC label 'D01'). Please disregard the product image.

VTI's SCP1000-D01 digital absolute pressure sensors are intended for barometric pressure measurement and altimeter applications for 30kPa...120kPa and -20C...70C measuring ranges. The pressure and temperature output data is calibrated and compensated internally and the communication between the SCP1000 and its host micro-controller is realized using an SPI interface.

SCP1000 is comprised of a VTI's 3D-MEMS capacitive sensing element, a dedicated low power CMOS interface ASIC with on-chip calibration memory, 4 preset measuring modes and a LCP (Liquid Crystal Plastic) MID (Molded Interconnect Device) housing. The component is a surface mountable device incorporating a circular vertical wall for easy waterproof sealing.

Four user selectable measuring modes combine 17-bit resolution (9cm of air column) with low or ultra-low power consumption, or alternatively 15-bit resolution (18cm of air column) with high speed data read (9Hz) or less than 5 A and power consumption. For example, at Low Power mode, the SCP1000 has an overall resolution of 2 Pa (15cm of air column) and a power consumption of 3.5A.

This unit comes in a newly developed plastic housing. Normal hot-air rework will destroy this sensor.

Note: If you plan on using this board in direct sunlight, we suggest purchasing the SCP1000 Gasket as shown below in the related items.
