V1.2 Description is below

Grove - IR Distance Interrupter V1.0

This IR Distance Interrupter features a high-sensitivity RFR-359F photoreflector to perform distance detection function. The photoreflector consists of a GaAs infared light emitting diode and a silicon planar phototransistor. When the infrared light emitted by the emitter gets reflected on a surface that blocked it, the phototransistor can pick up the signal for distance calculation. This module is panel mounted so that you can easily implement it on the surface of robots or other projects without wiring clutter. Also a potentiometer for adjustment and an indicator LED are arranged on the back for easy and clear use.

Features

High sensitivity photoreflector
Lightweight and compact
Panel mount design for clean and tidy implementation
Clear HID design: adjustment potentiometer and indicator LED

Application Ideas

Wanderer robots
RPM gauges
Approximation detection

Grove - IR Distance Interrupter V1.2

Description

Provided a high-sensitivity ITR9909 photo-reflector, Grove - IR Distance Interrupter v1.2 can be used to detect if there is an object presenting in front of it. The photo-reflector consists of a GaAs infared light emitting diode and a silicon planar phototransistor. When an object is placed right in front of the sensor, the reflective infrared light emitted from the emitter will be picked up by phototransistor and then outputs logical HIGH or logical LOW according to the distance between the reflection surface and the sensor.

By adjusting the potentiometer, you can set the detection threshold value in a range from about 90mm to 300mm if the reflection surface is a piece of white paper. An indicator LED is used to visualize the result of measurement as it will lights up bright red when an object is detected, and go off when there is nothing.
