MOS Ammonia Sensor

(0)

Environment Air Remediation Product Number : MICS-5914

Environmental Sensor

Applications

This application is to provide information on how to use SGX metal oxide sensors and to interpret the sensor responses. The information should be read in conjunction with the individual sensor datasheet and the other application notes found on the website. The areas covered are as follows:  Basic sensor principle and performance parameters – at the basic level providing qualitative response.  How to connect the sensors.  How to run the sensors, details of the type of test circuit and how to measure the output.  Warm up time.  Sensor Responses to gas need for calibration of individual sensors with target gas.  The effect of environmental factors, temperature, drift, flow rates etc.  Other performance parameters, cross-sensitivity, response time, sensor poisons, etc.
