Quantitative Ethylene Measurements with MOx Chemiresistive Sensors at Different Relative Air Humidities

open access: yesSensors, 2015
The sensitivity of two commercial metal oxide (MOx) sensors to ethylene is tested at different relative humidities. One sensor (MiCS-5914) is based on tungsten oxide, the other (MQ-3) on tin oxide.
