Work and pay attention to the phenomenon

Infrared emission tube outer black shrink tube is has the effect, must be tightly wrapped with infrared emission control, otherwise diffuse out of the infrared light can interfere with the infrared receiver, a direct impact on the output signal. Emission emission head is exposed to positive center, so you can narrow angle for distributing infrared emission control, it can effectively distance to the front obstacle detection, prevention to reduce interference.

After power-up, the board red LED will flash 3 times to enter the working state. When an obstacle is detected in front of the distance, the red LED will light up the board, otherwise the industry off, while SIG pin will output a low level signal, EN pin must be high under the premise. EN pins default to high to enable the sensor to work. If the board JP bridging is shorted, the first obstacle is detected ahead, the board red LED lights up, while SIG output low, until the front obstacle disappears, red LED output pin and SIG latch signal even before a state, that remain lit and low-level output signal; when the second (even-numbered) obstacle is detected, the red light goes off the board, while SIG transition to high signal output. Until the third (odd number) is detected, the latch state to shift.

This version 38KHZ obstacle avoidance module solves the same money or the same remote control infrared light interference, compared with the previous version of the article in the red part of the update adds section.

Sensitivity

The maximum detection range of 38KHz infrared obstacle avoidance module is 2 meters. However, if you use in this area of the sensor readings have triggered the error factor in the current environment, the board can be adjusted within the range potentiometer to reduce the detection range. Stable (latching) receiving distance 1.2 meters.
