Co-Mg ferrite nanocomposite as a humidity sensor device prepared by Co-Precipitation method

Abstract

In the present study, the humidity sensing properties of Co-Mg nanocomposite prepared by chemically coprecipitated have been investigated by impedance analysis. The correlation between the impedance patterns and relative humidity have shown remarkable results for further investigation. Whereas, the humidity measurement capability of the sensor was high at low frequencies. Also, we identified that this ability was continuously diminished at higher frequencies. So, the hysteresis value for successive adsorption and desorption of the humidity on ferrite nanocomposite material was also determined as small and also the long time measurement stability was excellent. The response and the recovery times for nanocomposite materials were identified as 60 s and 300 s respectively. Finally, a direct relationship between the active electron and transport mechanism of the humidity onto the nanocomposite has been identified as an advanced investigation.
