| - | ====== Infrared distance sensor ====== | ||
| - | This sensor from Sharp is a long-distance IR module; for IR this description is | ||
| - | accurate, though at other wavelengths it could act as a mid-distance module. The | ||
| - | distance that is easily sensed is 0.2–1.5 m. | ||
| - | The output of the sensor is an analogue signal of 2.7–0.5 V (corresponding to the | ||
| - | distance). The connection of the sensor is seen in Figures 1 and 2. One interesting | ||
| - | feature is the output of the module (see figure). The output of the sensor module | ||
| - | will be the same for 9 and 30 cm. This means that it is necessary to consider both the | ||
| - | slope of the signal and the direction of motion, to be sure of which side of the peak | ||
| - | you are on. | ||
