Distance sensor - wide-angle 3-channel + connectors - OPT3101 - Pololu 3680

Index: PLL-19101 EAN: 5904422366056
A wide-angle distance sensor from Pololu, featuring the 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, which in combination allow a FOV of about 180°. It uses the I2C bus to communicate with other modules. The module is also equipped with a 7-pin mounting connector to connect it to the TI-RSLK MAX platform. It operates with a voltage range of 2.7 V to 5.5 V.

The module detects objects in three zones.

Distance measurement in three zones

Sensor performs measurement inthree channelsTX0, TX1 and TX2. Their combination enables detection with a viewing angle ofapproximately 180°. Under favorable conditions, it can detect objectsup to 1 maway. The module emitsinfrared lightthanks to built-in LEDs. The returned value is thetime delay of the reflected signal, from which the distance of the object is calculated.
