Gorillacell Module 024: IR Object Sensor

Table of Contents

The Infrared Obstacle Avoidance Sensor works by emitting infrared light and detecting whether some of that light is reflected back to the sensor. When sufficient reflected light is detected, it indicates that an object is present in front of the sensor.

In this module, the transparent IR diode functions as the light transmitter, while the black IR diode serves as the light receiver. This principle allows the sensor to detect nearby obstacles without physical contact.

The Gorillacell ESP32 Development Kit includes one (1) IR Object Sensor module, enabling users to experiment with obstacle detection and autonomous navigation projects.

BASIC INFORMATION

Device Category Interface Chipset Description
Input Sensor Cell Digital - -

PINOUT

It has 3 pins which are

  1. G - for the ground pin,
  2. V - for the supply voltage, and
  3. S - for determining the state of the IR Object module.

An IR Object sensor produces a logic 1 when it detects a non-reflective surface (such as a black line) else it is logic 0 (reflective surface such as white).

IR Object sensor comes with a small trimmer resistor for adjusting the sensor sensitivity. Rotate it so that so that the LED D1 is not lit.
