Microwave Assisted Technique for Synthesizing ZnCdO Nanopowder Humidity Sensor

Now a days nano sensors place a vital role in sensi ng of smell less toxic gases which are polluting the environment. It s active role paved a path in protection of environments from the hazards. An attempt is made by using ZnCdO nanopowder humidity sensor. ZnCdO nanoparticles have been prepared by using a simple household microwave irradiation with an operating f requency of 2.45 GHZ. This technique permits us to produce gram quantity of inhomogenous nanoparticle in just 10min. The variat ion of conductivity in ZnCdO nanopowder ensures to analyze the sensor behavior easily and humidity controlled electronic devices. The samples were further subjected to photoluminescence (PL), Scanning electron microscope (SEM) studies. The humidity variations are observed inside the solar still alon g with the water temperature and air temperature. The performance ef ficiency of the sensor is studied and reported.
