Product description: Wide angle distance sensor 3 channel + connectors - OPT3101 - Pololu 3680
Wideangledistance sensorfrom Pololu, featuring theOPT3101chip from Texas Instruments. Detects thepresence of objectswithin a radius ofup to 1 mand measures their distance in three zones TX0, TX1 and TX2, which in combination allow aFOV of about 180°. It uses theI2Cbus to communicate with othermodules. It is also equipped with a 7-pin mounting connector to connect it to the TI-RSLK MAX platform. It works with a voltage rangefrom 2.7 V to 5.5 V.
Arduino compatible product
A detailed user guide andlibraryfor Arduino environment is available for download on GitHub on themanufacturer's website.
Distance sensor manufactured by Pololu.
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.
