Mobile Sensor that Quickly and Selectively Measures Ammonia Gas ...

used metal-oxide semiconductor gas-sensor devices can also detect ammonia. In these cases, the semi-conductor devices are used at a high temperature of around 300°C to raise the carrier density amount of the current flowing in a semiconductor and surface activity. Such condition enables the devices to be sensitive to ammonia, similar to other kind of gases. For the molecular recognition approach, …
