ข้อมูล GP2Y0A41SK Infrared Sensor Sharp GP2Y0A41SK Distance Sensor 4cm - 30cm
The GP2Y0A41SK0F is the shortest-range Sharp analog distance sensor we carry, featuring a detection range of 1.5″ to 12″ (4 cm to 30 cm). The shorter range gives you higher resolution measurements, and the lower minimum detection distance makes this sensor great for detecting very close objects. The distance is indicated by an analog voltage, making this sensor very easy to use.
The Sharp distance sensors are a popular choice for many projects that require accurate distance measurements. This IR sensor is more economical than sonar rangefinders, yet it provides much better performance than other IR alternatives. Interfacing to most microcontrollers is straightforward: the single analog output can be connected to an analog-to-digital converter for taking distance measurements, or the output can be connected to a comparator for threshold detection. The detection range of this version is approximately 4 cm to 30 cm (1.5″ to 12″); a plot of distance versus output voltage is shown below.
The GP2Y0A41SK0F uses a 3-pin JST connector that connects to our 3-pin JST cable for Sharp distance sensors (not included). It is also simple to solder three wires to the sensor where the connector pins are mounted (see picture). When looking at the back, the three connections from left to right are power, ground, and the output signal.
