Gas sensors are widely used in devices known as electronic Noses. Which are used for the detection of gas leaks, environmental quality and food, etc. However, it is necessary to perform a quantitative and qualitative analysis of these sensors based on the measurement of their response to obtain their characterization. In the present work is shown the design and implementation of a measurement system for gas sensors response. Therefore, a sealed stainless-steel chamber that internally contains the sensors is designed. On the other hand, a temperature controller is implemented using a PID controller governed by an interface developed using virtual instrumentation software. Particularly, this system has the ability to measure the response of gas sensors, such as: metal-oxide and quartz crystal microbalance. The development of this project, presents an alternative to measure the response of sensors to commercial, contemplating a lower cost and same functionality. Measurements were performed at different temperatures, applying samples of ethanol, obtaining typical results in the response of this type of gas sensors. Therefore, it can be said that the system operates satisfactorily.
