Understanding a Gas Sensor | Jaycon Systems

09/05/2016· Since the heater of the sensor draws a lot of current and the sensor needs 5V to work properly, it is better if you use an external power supply that assures you a voltage input of 5V with enough current for the heater (The Arduino provided a little less than when tested). The Arduino Mini Pro has an internal 5V regulator, so you can connect an external power supply (no more than 12V) to ...

Highly Sensitive and Selective VOC Sensor Systems Based on ...

The voltage across the sensor layer is limited, typically to ≤1 V, to prevent unwanted effects such as electromigration in the layer leading to sensor drift. However, this voltage limit (or more exactly the maximum field strength) also depends on the operating temperature, allowing higher voltages and thus more sensitive measurement at low temperature. Thus, electronics are required that ...
