Ranging Distance Detecting Ultrasonic Sensor Display Module

Features:

• Ultrasonic display module use small microcomputer system controller ,use STC 10F04XE, fully compatible with 51 microcontroller
• IO port output pins, two switch output terminal, three key features, three digital display.
• With DS18B20 temperature compensation circuit Contact Interface
• Ultrasonic Ranging Module can be used directly measured the distance, you can set the distance alarm.
• The system can provide ranging program can display panel of the schematic diagram.
• Wide-voltage : DC 6~12V
• Work current : 45mA
• Range : 0 ~ 400 cm
• Maximum measurement distance : 500cm
• Test object : about the size of 6cm
• Size: 45 * 44 * 12 mm

Switch Output:

• this module's outputs can be user-defined
• Press and hold S1 button for 3 seconds, showing LLL
• Press the S1 key, displays a number (eg 001), Is the smallest measurement distance. When the measured distance is less than this value,OUT2 will output a high level(4.5V)
• this value can adjustable, use S2 + , use S3 --, to change.
• When setting the minimum measured value end, then click the S1 key, the display appears HHH, can set Max distance value, Press the S1 key, displays a number (eg 200), Is the max measurement distance.When measuring the distance is greater than this value, OUT1 will output a high level (4.5V). this value can adjustable, use S2 + , use S3 --, to change.
• when setting is end. press the S1 key,Save this value. With power-down memory function.
