The room temperature operating resistive ammonia gas sensor is designed by using an upright-standing ZnO nano-sheets. Wet chemical route is preferred for growing ZnO upright-standing free nano-sheets of ~2-5 μm in length and ~100-150 nm in width. Structural, surface morphological and room temperature ammonium sensing properties of these nano-plates are elucidated. Well-resolved nano-sheets when kept in ammonium container showing good sensing behavior. Ammonia gas sensor response measured room
