Pololu 3-Channel Wide FOV Time-of-Flight Distance Sensor for TI-RSLK MAX Using OPT3101

Pololu 3-Channel Wide FOV Time-of-Flight Distance Sensor for TI-RSLK MAX Using OPT3101

This board is a 3-channel time-of-flight proximity and distance sensor module based on the OPT3101 IC from Texas Instruments. It emits infrared light in one of three selectable directions with its six integrated LEDs and measures distance by measuring the time delay of the reflected signal. Distance measurements can be read through a digital I²C interface. The module is designed to mount to the front of the TI-RSLK MAX robot. The combined field of view of the three sensing zones is almost 180 degrees, and the maximum range is about one meter.

Overview

This board is a 3-channel time-of-flight proximity and distance sensor module based on the OPT3101 IC from Texas Instruments. Unlike conventional IR sensors that use the intensity of reflected light to estimate the distance to an object, this board emits 940 nm infrared light pulsed at 10 MHz, and then measures the phase (delay) of the reflected signal, which corresponds to the distance to the target object. It also measures the amplitude of the signal, which indicates how bright/reflective/close the object is.

This board has three channels that each cover approximately 50° to 60°, giving the sensor a wide field of view (FOV). In favorable conditions, the sensor can measure objects at distances up to 1 m. Distance measurements are available through the sensor’s I²C interface, which is also used to configure the sensor.

This module is designed to be mounted onto the 7-pin connector on the front of a TI-RSLK MAX chassis board, but it can be used with any I²C-capable device. The board can be powered from a 2.5 V to 5.5 V supply. On-board regulators supply the 3.3 V logic voltage to the OPT3101. The board includes a circuit that shifts the I²C clock and data lines to the same logic voltage level as the supplied VIN, making it simple to interface the board with 3.3 V or 5 V systems, and the board’s 0.1? pin spacing makes it easy to use with standard solderless breadboards and 0.1? perfboards.

Details for item #3680

This product ships fully populated with its SMD components (including the OPT3101) and through-hole male header pins. A 7-pin female header and two mounting screws (#2-56, 5/8?) and nuts are also included, as shown in the main product picture. We also carry a version of this module without headers.
