DIY Ultrasonic Ranging Module Radar Alarm Kit Based on 51 Single Chip For Arduino
$14.57
Note: This kit need to assemble, not supply instructions.
Feature:
1, Key Description: From the first on the left, – key, + key, setting key.
2, SCM model: STC89C52.
3, Can set the alarm distance, press the set button, you can press plus, minus key, you can modify the alarm distance, and has power-off save function.
4, When the measured distance is less than the set distance, the buzzer will alarm.
