1. Get started quickly in gas sensor instrument design using Infrared Gas Sensors from e2v Simply attach the universal power supply connect to a PC USB port and plug in an e2v infrared gas sensor The e2v 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 e2v IR EK2 Gas Sensor Evaluation Kit will drive the e2v 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 e2v 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 full2.
