Replacement:COM-09603. Although there is not a drop-in replacement, the BMP085 is a suitable replacement for most applications. This page is for reference only.

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 -20°C...70°C 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 5µA 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 3.5µA.

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.
