Obstacle Avoidance Sensor (ST1081)

1. Introduction

Infrared obstacle avoidance sensor is designed for the design of a wheeled robot

obstacle avoidance sensor distance adjustable. This ambient light sensor adaptable,

high precision, having a pair of infrared transmitter and receiver, transmitter tubes

emit a certain frequency of infrared, When detecting the direction of an obstacle

(reflector), the infrared receiver tube receiver is reflected back, when the indicator is

lit, Through the circuit, the signal output interface output digital signal that can be

detected by means of potentiometer knob to adjust the distance, the effective

distance From 2 ~ 40cm, working voltage of 3.3V-5V, operating voltage range as broad,

relatively large fluctuations in the power supply voltage of the situation Stable

condition and still work for a variety of microcontrollers, Arduino controller, BS2

controller, attached to the robot that

Can sense changes in their surroundings.

Specification:

 Working voltage: DC 3.3V-5V

 Working current: ≥ 20mA

 Operating temperature: -10 ℃ - +50 ℃

 detection distance :2-40cm

 IO Interface: 4-wire interfaces (- / + / S / EN)

 Output signal: TTL level (low level there is an obstacle, no obstacle high)

 Adjustment: adjustable resistance

 Effective angle: 35 °

 Size: 45*16*10mm

 Weight Size: 9g

Pinout Pin “+” Gnd out EN Description Power(3.3V~5V DC) ground Signal pin Enable pin that Low level works, usually useless 3.Example Here is a small example to test the sensor. By default, the sensor returns 1 on the Serial Monitor. When detecting something, the sensor return 0. The connection as below: ******Code begin****** int count; void setup() { Serial.begin (9600); pinMode (9, INPUT); //Sensor output } void loop() { www.openplatform.
