Beschreibungen/Notizen

• The liquid petroleum (LP) gas leakage detector was successfully fabricated using modified nanostructured ZnO thin film as the sensitive layer. The detector consists of ZnO sensitive layer, a heater, a comparator, a transistor, an LED and a buzzer. The detector has the switch system where the comparator can change the current through the LED and buzzers when the LP gas is detected. The ZnO thin films were fabricated by sol gel method using chemical bath deposition technique at moderate temperature on an alumina substrate with electrode contacts. This sensors system allows us to produce LP gas sensor with a relatively low-cost procedure. The detector was tested with the LP gas leakages and had shown good response values as measured at the operational temperature of 200o C.
