The photosensitive sensor is a sensor that converts the optical signal into electrical signal with the photosensitive element
"The working principle of a photosensitive sensor . The photosensitive sensor is a sensor that converts the optical signal into electrical signal with the photosensitive element, and its sensitive wavelength is near the visible wavelength, including the infrared wavelength and ultraviolet wavelength. Photosensitive sensor is not limited to the detection of light, it can be as a detection element composed of other sensors, to detect the number of non electric, as long as these non electricity into light signal change can be. Light is provided with a photoelectric tube with high precision, the photoelectric tube has a small needle plate by "two tube" which, when the fixed pressure to the photoelectric tube is applied on both ends of a reverse impact on it, any photon will lead to the release of the electronic result, when the light intensity is high current, photoelectric tube is also bigger, the current through a resistor, the voltage across the resistor is converted into a 0-5V voltage DAC collector can be accepted, and then collected in an appropriate form to save the results down. Simply put, the photosensitive sensor is the use of photosensitive resistance by light intensity effect and principle the resistance change to analog signal for the robot host sends light intensity. Photosensitive sensor is one of the most output and widely used sensors, and it plays an important role in the automatic control and the non electric measurement technology.. Photosensitive sensor is mainly used in solar lawn lamp, light controlled Nightlight, camera, monitor, light controlled toys, sound light controlled switch, camera, anti-theft wallet, photocontrolled music box, birthday music candle, music Cup, a human body induction lamp, a human body induction switch electronic products light automatic control field. The function is very strong. Delivery list: 1 Photosensitive sensor module *1 2. 3 PIN DuPont line *1
