Distance sensor - wide-angle 3-channel - OPT3101 - Pololu 3412

Index: PLL-19104 EAN: 5904422365882
Wide angle distance sensor manufactured by Pololu, It is equipped with OPT3101 chip from Texas Instruments. It detects the presence of objects within a radius of up to 1 m and measures their distance in three zones TX0, TX1 and TX2. The measurement obtained from the three zones provides an FOV of approximately 180°. The sensor uses the I2C bus to communicate with other modules. The leads are solder fields where goldpin connectors should be soldered. The module operates with a voltage range from 2.5 V to 5.5 V.

Module detects objects in three zones.

Distance measurement in three zones

Sensor performs measurement inthree channelsTX0, TX1 and TX2. Their combination allows detection with a viewing angle ofapproximately 180°. In favourable conditions, it can detect objectsup toa radius of1 m. The module emitsinfrared lightthanks to built-in LEDs. The returned value is thetime delay of the reflected signal, based on which the distance of the detected object is calculated.
