ECVQ-EK3中文资料MINIATURE CATALYTIC AND ELECTROCHEMICAL GAS SENSOR EVALUATION KIT数据手册SGX规格书

描述 Description

The SGX IR-EK2 Gas Sensor Evaluation Kit will drive the
SGX range of infrared gas sensors and automatically
measure the sensor outputs and calculate gas concentration
levels.
Sensors can be controlled automatically via the USB
interface with an easy-to-use control and data logging PC
application provided on CD. Alternatively a terminal program
such as HyperTerminal can be used to send simple
commands to the on-board microcontroller. The user
manual provides a comprehensive set of commands.
The PCB provides sockets for use with SGX 6- and 7-pin
(single gas) or 8-pin (twin gas) infrared gas sensors. For
devices which do not have integrated temperature
monitoring, a temperature sensing IC is provided on the
PCB close to the gas sensor socket positions.
The evaluation kit allows experimentation with different bulb
drive voltages. Reference and active channel gains can also
be adjusted or set to a fixed level. This allows operation with
the full range of SGX infrared gas sensors. Sensors can be
calibrated and then the gas concentration levels monitored.
An expansion connector provides access to four
configurable alarms (open collector), two analog outputs
and four digital inputs. LEDs on the board mimic the status
of each alarm. A JTAG header allows advanced users to
upload their own software to the microcontroller
(MSP430F2616) and make full use of the available
interfaces.
A universal mains adapter is also supplied or the user may
connect a 9 V power supply to the terminal block connector.
