Feature:
1. [38KHZ INFRARED DETECTION] The non logic chip oscillation frequency is adjusted to 38KHz detection circuit, which can avoid the interference of infrared light from the radio or remote control.
2. [MULTIPLE MOUNT METHODS] The sensor module has vertical and horizontal installation welding methods, which greatly expanding the scope of application.
3. [WITH ENABLE PORT] Sensor detection with enable port, convenient for signal line as a bus application, sensor enable detection output signal.
4. [EEPROM RECORD] Use EEPROM to record the working conditions of each module, reducing the probability of mutual interference of the same model to 1percent .
5. [WITH LATCH FUNCTION] On board setting jumper JP, the signal output has a latch function when it is short circuited, otherwise it is a jog output.
6. [WIDE APPLICATION] The detection range can reach 1.2 meters away, with pin SIP header, which can be used in breadboard or through hole projects.
Specification:
Item Type: Infrared Obstacle Avoidance Sensor
Power Requirements: 5V DC
Communication: Digital high or low output
Operating Temperature: 32 158 Fahrenheit (0 70 celsius )
Product Size: Approx. 2.4 x 2.8cm 0.9 x 1.1in
Application: Warehouse door control lighting switch (lock setting), security trigger alarm system, automatic production line transportation belt object count, robot control, etc.
Sensitivity: The maximum detection distance of the infrared 38KHz obstacle avoidance module is 2 meters. If the sensor triggers false readings under the current environmental factors, the on board potentiometer can be adjusted within this range to shorten the detection range. The stable (latch) receiving distance is approx 1.2 meter 3.9ft
Pin Description:
GND: Power supply negative pole
VCC: Power supply 5VDC positive pole
SIG: Signal output pin
EN: Signal output enable pin

Note:
1. The black heat shrinkable tube on the outer layer of the infrared emitting tube is very useful, and the infrared emitting tube must be tightly wrapped, otherwise the diffusely reflected infrared light will interfere with the infrared receiving head and directly affect the signal output. The transmitter head only needs to expose the exact center point of the transmitter, so that the emission angle of the infrared transmitter tube can be reduced, and the obstacles in front can be effectively detected at a long distance to prevent and reduce interference.2. After power on, the red LED on the board will flash 3 times and enter the working state. When an obstacle is detected in the front distance, the red LED on the board will light up, otherwise the industry will go out, and the SIG pin will output a low level signal, and the EN pin must be high. The EN pin is high by default, which enables the sensor to work. If the JP tin bridge on the board is short circuited, when an obstacle is detected in the front for the first time, the red LED on the board will light up, and the SIG will output low level. When the obstacle disappears, the red LED and SIG pin will output The signal is evenly latched in the previous state, that is, it remains lit and low level signal output; when an obstacle is detected for the second time (even times), the red light on the board goes out, and the SIG changes to a high level signal output. The latched state does not change until the third time (odd number of times) is detected.
