Optical sensors are transducers that convert light into electrical signals. There are many types of optical sensors, such as photoresistors, photodiodes, phototransistors, etc. One of the most popular optical sensors, due to its versatility and reliability, is the SFH 9206 reflective analog output optical sensor. This article describes the application field and working principle of the SFH 9206 reflective analog output optical sensor.
Application Field
The SFH 9206 is a low-cost reflective optical sensor that utilizes a silicon photocell to detect ambient light levels. It has an integrated amplifier to provide a proportional analog output that is highly sensitive from 0.1 lux up to 10,000 lux. It is primarily used for short-range distance measurements and detecting the presence or absence of light. The SFH 9206 is widely used in a variety of applications, including automotive lighting, home automation, floor lighting, and outdoor lighting, among others.
Working Principle
The SFH 9206 works by using a light source to illuminate a target object and then measuring the amount of reflected light using the integrated photocell. The amount of light reflected is then converted into an electrical signal and is amplified and output as an analog voltage. The output voltage is proportional to the amount of reflected light and can be used to measure distance or presence/absence of a target object.
The SFH 9206 is designed to be used in a reflective mode, meaning that it is best suited for short-range distance measurements. When the light is reflected off a target object, the photocell measures the intensity of the reflected light and the output voltage is proportional to the amount of light intensity. This makes the SFH 9206 ideal for distance measurement applications, as the greater the distance, the less light that is reflected and thus the lower the output voltage.
Moreover, the SFH 9206 is also able to detect the presence/absence of a target object when used in a non-reflective mode. In this mode, the SFH 9206 measures the amount of ambient light and when the target object is present, it blocks the ambient light from reaching the photocell and thus reducing the output voltage. This makes the SFH 9206 ideal for applications requiring the detection of the presence/absence of an object.
Overall, the SFH 9206 is a versatile and reliable optical sensor that is widely used for short-range distance measurements and detecting the presence/absence of a target object. It is a low-cost solution that is easy to integrate into any system, making it an ideal choice for a variety of applications.
