This is a long distance range detection sensor based on PIR fundamentals, the sensor is a passive type infrared distance sensing sensor, with sensing capability of 12meter; the sensor uses the infrared detection chip to detect the infrared radiation emitted by the distant physical object.Nearly every physical objects whether living or non-living objects emits heat radiation in the form of infrared radiation. This unique property of heat radiation signature of every physical object helps the PIR sensor to detect the motion in this case EKMC1603112 uses it to calculate the distance of the physical object, the sensor is covered with black lens with low noise circuitry, an digital output of the sensor is further used by microcontroller to help in making alarm or switching any kind of AC/DC devices. PIR HC- SR501 uses best quality Fresnel lens in order to cover wide angle of detection, with additional features of adjustable sensitivity and delay, the device runs between 4.5 volt to 20 volt, with the output voltage of 3.3 volt when HIGH and 0 volt when LOW.
