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 1%. 5、[WITH LATCH FUNCTION] On board setting jumper , 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. Item Type: Infrared Obstacle Avoidance Sensor Power Requirements: 5V DC Communication: Digital high or low output Operating Temperature: 32-158℉(0-70℃) 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 1 x Infrared Obstacle Avoidance Sensor
