Infrared obstacle avoidance module-IR333-PT333

Overview

product description

This module uses infrared transmitter IR333C to emit infrared light, PT333-3B-L receives reflected infrared light, and compares it through comparator LM393 to determine whether there is any obstacle ahead.

Features

Working voltage: 3.3V / 5V recommended (<10V is acceptable)
Module power consumption: 25mA～40mA
Detection distance: <=30cm (adjustable through adjustable resistor )
Indicator light: power light + obstacle indicator light
