Preparation and characterisation of NH gas sensor based on nanocomposite.

was synthesised by the process. The produced powders were characterised by , , , , and tests. The sensors' function was based on with thin film deposited on top of interdigitated electrodes (). detection with nanocomposite sensor could be successfully performed even at room temperature (RT) and relative humidity of 45 %. Results demonstrated that might be promising sensing materials for detecting the low concentration (ppm). In addition, the sensor is selective to the interfering gases, including , and . This sensor displays acceptable repeatability and stability over time.
