  • Rashidi Salim, Mohd; Haniff Ibrahim, Mohd; Izam Azmi, Asrul; Yusof Mohd Noor, Muhammad; Sharmi Abdullah, Ahmad; Hafizah Ngajikin, Nor; Manap, Hadi; Dooly, Gerard; Lewis, Elfed (Faculty of Electronic and Computer Engineering (FKEKK), Universiti Teknikal Malaysia Melaka (UTeM)., 2018)
    An improved and compact gas sensor using mid-infrared spectroscopy for highly responsive Carbon Dioxide (CO2) detection is presented. The sensing principle is based on open-path direct absorption spectroscopy in the ...
  • Dooly, Gerard; Manap, Hadi; O'Keeffe, Sinéad; Lewis, Elfed (Elsevier, 2011)
    A highly selective optical fibre sensor has been developed for the monitoring of low level atmospheric ammonia concentrations. The measuring technique employed is based on a differential optical absorption approach, which ...
  • Dooly, Gerard; Manap, Hadi; O'Keeffe, Sinéad; Lewis, Elfed (IOP Publishing, 2011)
    An optical fibre sensor for the monitoring of low level atmospheric ammonia concentrations is presented. The measuring technique employed is based on a differential optical absorption approach, rather than a semiconductor ...
  • Manap, Hadi (University of Limerick, 2011)
    This thesis describes an optical fibre sensor to detect and accurately measure ammonia gas in the agricultural sector. Increases in ammonia emission especially from the farming industry have created the need for a sensor ...
