3-Channel Wide FOV Time-of-Flight Distance Sensor Using OPT3101 (No Headers)
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 combined field of view of the three sensing zones is almost 180 degrees, and the maximum range is about one meter.
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.
