MICS-EK1 Datasheet
Metal Oxide Semiconductor Gas Sensor Evaluation Kit
Getting started quickly with SGX Metal Oxide Semiconductor Gas Sensors
Simply attach the universal power supply, connect to a PC
USB port and plug in one or two gas sensors. The SGX data
logging and control software allows the performance of
different sensors to be assessed and makes it easy to
capture performance data.
INTRODUCTION
The SGX MICS-EK1 Gas Sensor Evaluation Kit will drive
the SGX range of Metal Oxide Semiconductor gas sensors
and automatically measure the sensor resistance as it
changes with applied gas.
Sensors can be driven manually or automatically by sending
simple commands through the USB interface to an on-board
microcontroller. A comprehensive set of commands is
provided for use with a terminal program such as
HyperTerminal. Alternatively an easy-to-use control and
data logging PC application is provided on CD which gives
full functionality in a few mouse-clicks.
Surface mount adapter boards are also available with the kit
and can be ordered separately. One adapter PCB will plug
in to both sockets and can be fitted with either a single or
dual surface mount gas sensor.
The heaters can be set to two levels. These are nominally
preset to 43 mW and 76 mW by plug-in resistors but may be
changed by the user to other values. The microprocessor
monitors the sensor output resistance with automatic
resistance range switching.
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.
