Gas sensors are primarily used in the gas and oil industry and have a very commercial value due to its higher sensitivity properties in detecting minor leakage. As the sensors heterojunction are composed of combination metal oxide and organic polymer, the use of sensor would expect upgrade in term of their sensitivity, selectivity and stability. Two methods used for heterojunction fabrication are chemical bath deposition and electrodeposition. The sensors sample are tested based on I-V characteristic would inevitably inflict low current values. In this experimental work, MgO was employed due to its high conductivity and lower operating cost while polyaniline was used due to its high mechanical strength. Two different gases were used, which are LPG and CO2 respectively. Preliminary results showed that the sensor sample was successfully giving the conductivity effect. Further studies also revealed that the response time of sensor was mainly influenced by the different concentration of gases used. The higher gas response for LPG is 45% while for CO2 is 55%. Low concentration of the gases can be improved in future study by carrying out the larger scale of sensing chamber. |
