Analog distance sensors

Analog distance sensors

Sensors odbiciowe

Sensors odbiciowe also called it reflective photoelectric sensorsin which the light beam is directed through the sensor is reflected from within a certain distance (depends on specific sensor) with led floodlight. Interruption of this beam of light through the object causes a change in the output signal of the sensor. The spotlight of such a sensor may be a passive element - a mirror (mirror) or an active receiver. Often nadawczym element is an led, the receiver and fototranzystor. Noteworthy are the miniature sensors analog distance with analog output series Pololu QTR-L-1A operating in the infrared range. The sensor consists of a transmitter and receiver with a size of 7.6 x 8.9 x 3.1 mm and weighing only 0.2 g. With analog output, depending on the distance between transmitter and receiver, as well as color, obstacles, located between them, generates at its output the voltage value. The sensor is ideally suited in systems in vehicles and robots, which require the ability to track the path as a motion path.

Contactless sensors

Analog distance sensors with analog output, in which the sensor responds to the change of the input signal when approaching an obstacle, the sensors are non-contact. Be for You great solution in case when you want Your robot or other vehicle has been detected an object in its path and could determine its distance in relation to it. Botland offers analog distance sensor Sharp series GP2Y that operate in bands from 2 to 15 cm, to in the range of 100 to 550 cm! If you need exact measurement, select the sensor series HSDL, which detects obstacles at a distance of 0 to 60 mm.
