Luxmeter Design with Proximity Sensor to Efficiently Test Light Intensity and Distance on Lamp Operation in Hospitals

The lighting of the operating/surgical site depends on quality from overhead light source and reflection curtain. Light measurement operating table is very necessary because it generates that irradiated into cutting wound without dazzling surface so pathological conditions can be recognized must provide depth contrast anatomical relationships, to ensure this proper calibration method needed. Long-term use medical devices cause changes in accuracy. Therefore, author makes a tool measure intensity which equipped with distance meter. purpose study was develop measuring instrument for lamps, namely luxmeter by making Luxmeter TFT Display Distance Sensor. This uses an ultrasonic sensor HC-SR04 between module MAX44009 lamp displayed screen. Based setting roll meter, error value Surabaya electromedical engineering workshop at 75 cm meter 0.0127% 100 0.0045%. rate results getting 0.082% lux workshop, is, 0.055%. design proximity assist learning process more effective will electromedics testing lamps hospitals efficient.
