MPPT0650-DCLiR is a sort of PIR LED light solar controller.
It is fit for 12V system voltage, 6A maximum charging current, 50W maximum load power and 20~45V Output voltage range.
MPPT0650-DCLiR is based on the technology of infrared automatic control products. When someone enters the induction range, the special sensors will detect the change of the human body infrared spectrum, then automatically connected to the load. If people don't leave the induction range, the light will be continuous light. When the person leaves, the load will be automatically turned off. MPPT0650-DCLiR is a really friendly and convenient, safe and energy-saving PIR LED light solar controller.
PIR is the abbreviation of Passive Infrared, which is passive infrared technology.
The full name of the PIR detector is “Passive Infrared Detection”, that is, passive infrared detectors or body sensors, sometimes called “Passive Infrared Sensor”.
There are two key components in passive infrared detectors，one is pyroelectric infrared sensors (PIR)，It can transfer the infrared signal between 8-12um wavelength into electrical signal, and can restrain the white light signal in the nature. Therefore, in the passive infrared detector's guard area, when the human body does not move, the pyroelectric infrared sensor induces the background temperature only. When the human body enters the guard area, the pyroelectric infrared sensor induces the difference signal between the human body temperature and the background temperature through the Finel lens. Therefore, the basic concept of infrared detection is to induce the temperature difference between moving objects and background objects.
Another device of the PIR LED light solar controller is the Finel lens. There are two forms of Finel lens, namely refraction and reflection. The Finel lens has two functions: The first is the focusing effect, that is the pyroelectric infrared signal is refracted (reflected) on the PIR; The second is to make the alert area divide into many bright areas and dark areas, which can transfer the moving objects in the alert area to the form of temperature changing to produce changing infrared signal on PIR. In this way, the PIR generates a varying electrical signal.
