danodonovan 25:c5bff546082f 9 # Overview {#overview}
danodonovan 25:c5bff546082f 10 ADISENSE product family provide complete, flexible and versatile measurement
danodonovan 25:c5bff546082f 11 solutions for a wide range of both compensated and uncompensated analog or
danodonovan 25:c5bff546082f 12 digital sensors. The ADSNS1000 is the first product in this portfolio. The
danodonovan 25:c5bff546082f 13 ADSNS1000 module seamlessly interfaces to temperature, pressure, humidity,
danodonovan 25:c5bff546082f 14 acceleration and multiple other sensors. The module has all the building blocks
danodonovan 25:c5bff546082f 15 to excite, measure and correct each sensor and generate an output in sensor
danodonovan 25:c5bff546082f 16 related units such as oC, oF, psi, %RH. In conjunction with the MeasureWare
danodonovan 25:c5bff546082f 17 ecosystem, ADSNS1000 can be easily configured and optimised for the sensor types
danodonovan 25:c5bff546082f 18 selected to meet the accuracy and measurement times required.
danodonovan 25:c5bff546082f 19
danodonovan 25:c5bff546082f 20 The ADSNS1000 provides up to 11 measurement channels. The module has 4
danodonovan 25:c5bff546082f 21 measurement inputs that connect to uncompensated analog sensors. It also
danodonovan 25:c5bff546082f 22 includes two dedicated analog measurement inputs for temperature compensation
danodonovan 25:c5bff546082f 23 such as cold junction compensation of the thermocouples. ADSNS1000 includes a
danodonovan 25:c5bff546082f 24 0-10V measurement input, 0-20mA measurement input, two I2C measurement inputs
danodonovan 25:c5bff546082f 25 and one SPI measurement input also which are useful for compensated sensors such
danodonovan 25:c5bff546082f 26 as pressure, humidity and accelerometers.
danodonovan 25:c5bff546082f 27
danodonovan 25:c5bff546082f 28 The ADSNS1000 communicates to the host application processor via a dedicated SPI
danodonovan 25:c5bff546082f 29 interface. The ADSNS1000 operates as a slave device when communicating with the
danodonovan 25:c5bff546082f 30 host application processor.
danodonovan 25:c5bff546082f 31
danodonovan 25:c5bff546082f 32 The ADSNS1000 host application library currently includes support for the
Dan O'Donovan 31:de49744b57a6 33 ADSNS1000 module when used in conjunction with the ST Nucleo F411RE /
Dan O'Donovan 31:de49744b57a6 34 EV-COG-AD4050LZ host application processor running in the Arm Mbed development
Dan O'Donovan 31:de49744b57a6 35 environment.

danodonovan 25:c5bff546082f 38 ## Host Communication Interfaces {#interfaces_hostcommunication}
danodonovan 25:c5bff546082f 39 The interfaces in this section enable the connectivity with the host application
danodonovan 25:c5bff546082f 40 processor which is responsible for communication, configuration and control of
danodonovan 25:c5bff546082f 41 the ADSNS1000 module. Platform specific host connection parameters may be
danodonovan 25:c5bff546082f 42 specified via the [ADI_SENSE_CONNECTION](@ref ADI_SENSE_CONNECTION) structure on
danodonovan 25:c5bff546082f 43 the [ADISENSE API](@ref ADISENSE_Api) and low-level connectivity is accessed via
danodonovan 25:c5bff546082f 44 the [ADISENSE Host Portability Layer](@ref ADISENSE_Host).
