The E18-D80NK Adjustable Infrared Sensor Switch 3-80cm is a set of transmitter and receiver in one of the photoelectric switch sensor.
The detection distance can be adjusted according to the demand. The sensor has a detection range of 3-80cm.
The Adjustable Infrared Sensor Switch is small, easy to use, inexpensive, easy to assemble and can be widely used in a robot to avoid obstacles, interactive media, industrial assembly lines, and many other occasions.
The switching signal output differs in accordance with the obstacles. It remains high when no obstacles and remains low when there are obstacles. There is a bright light behind the probe to detect the scope of 3cm – 80cm.
GP2Y0A21YK0F 10-80CM IR Distance Sensor + Cable AB064
For original product select sold and fulfilled output type: analog;when the voltage is different from the – output difference (typical):1.9v @ 10 ~ 80cm;voltage – supply:4.5 v ~ 5.5 v;gp2y0a21yk0f optical sensor, detection distance 10-80cm
Output signal: Electric frequency signal, high level 5V, low level 0V.
Sensor angle: Not more than 15 degrees.
Detection distance: 2cm~450cm.
High precision: Up to 3mm
Mode of connection: VCC / trig(T) / echo(R) / GND
Module Working Principle:
Adopt IO trigger through supplying at least 10us sequence of high level signal
The module automatically send eight 40khz square wave and automatically detect whether receive the returning pulse signal
If there is signals returning, through outputting high level and the time of high level continuing is the time of that from the ultrasonic transmitting to receiving
Designed with reflected infrared sensor, indicator light.
Built in a potentiometer for sensitivity control.
On-board LM393 voltage comparator chip and infrared sensing probe TCRT5000L
Support 5 V / 3.5 V voltage input
On-board signal output instructions, output is high effective signal at the same time, the indicator lamp light output signal can be directly and single-chip microcomputer IO connection & middot;
Signal detection sensitivity can adjust
Reserve all the way more circuits (P3 voltage drawn)
