Velleman VMA330 IR Obstacle Avoidance Sensor Module

This module is an inexpensive solution for an obstacle avoidance sensor, perfect for robotic projects and very easy to interface directly with Arduino® and compatible boards. The module has two potentiometers, one to control frequency and one to control the intensity.operating voltage: 3.3 V to 5 Voutput: digital (on/off)detection threshold: adjustable by 2 trimmersdistance range: 2 to 10 cmadjustment R6: frequency adjustment 38 KHz (already optimised)adjustment R5: IR LED power adjustment (already optimised)operating temperature: -10°C to +50°Ceffective angle: 35°I/O interface: 4 wire interface (- / + / S / EN )dimensions: 45 x 16 x 10 mmweight: 9 g
