SGX Europe Sp. z o.o. Building 11 Ligocka St. 103, 40-568 Katowice, Poland T: +48 (0) 32 438 4778 E: sales.is@sgxsensortech.com www.sgxsensortech.com IR-EK2 Datasheet Infrared Gas Sensor Evaluation Kit Get started quickly in gas sensor instrument design using Infrared Gas Sensors from SGX. Simply attach the universal power supply, connect to a PC USB port and plug in an SGX infrared gas sensor. The SGX data logging and control software allows the performance of single gas or twin gas sensors to be assessed and makes it easy to capture performance data. Users can experiment with different settings before designing their own instrument. Circuit diagram and parts list supplied. INTRODUCTION 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.
