The EE-SY201 optical sensor is a reflective analog output type sensor that is designed to detect changes in the environment. The device is equipped with two separate Infrared (IR) detector elements that are used to measure distance. The output is a linear 0.2 mV/cm voltage signal.

This optical sensor is suitable for many different applications, such as dimensional measurement, position sensing, motion detection, and object tracking. It is also suitable for use in robotics, as it is able to detect objects from a distance. Further applications can be found in laboratory and medical use, as well as in consumer electronics.

The EE-SY201 utilizes an IR semiconductor to enable its reflective analog output. The sensor operates on the principle of detecting the reflected sunlight from an object. The IR semiconductor by changing the background surface with respect to its dynamic characteristics gives a voltage signal in response to the change in the reflectivity of the object it is looking at.

The device is controlled by an integrated circuit (IC) that makes it capable of responding to small changes in luminosity caused by the object being detected. This capability is further enhanced by the presence of a compensation circuit that adjusts the sensitivity for maintaining a constant voltage output regardless of ambient light conditions.

Apart from the analog output, the EE-SY201 also has an analog signal output that can be used to provide a trigger action. The stored trigger data can then be used in applications like motion detection to calculate distance, object tracking, or in robotics for navigation purposes. It can also be used in combination with limit switches to verify the objects’ size, shape, and position.

In a traditional analog output optical sensor, an array of photocells must be connected and calibrated to generate distances accurately. The EE-SY201 utilizes a proprietary Adaptive Light Intensity Measurement (ALIM) selectable system that eliminates the need for calibration, making it highly accurate and reliable.The ALIM system also makes the EE-SY201 compatible with multiple infrared sources, such as sunlight, halogen lamps, and laser sources. All sources are filtered by the built-in filters which detects the band of interest and blocks all other sources of interference. This ensures low power consumption and improved signal to noise ratio

The EE-SY201 is available in 4 configurations – Single Layer, Dual Layer, and 2-Channel Type, which provide a range from 5-150 cm. Each version is also equipped with an LED and an audible buzzer to indicate the detection of an object. The average current consumption of the EE-SY201 ranges from 1.8 mA to 3.2 mA, which makes it suitable for battery-operated applications.

In conclusion, the EE-SY201 optical sensor is an excellent solution for many different applications as it provides a highly accurate and reliable reflective analog output signal in a compact form factor. The Adaptive Light Intensity Measurement (ALIM) system takes away the need for calibration, and the low current consumption makes it ideal for battery-operated devices.
