Description: 1.1 功能简介
三种测距模式选择跳线J1（短距、中距、可调距）：
短距：20cm~100cm左右（根据被测物表面材料决定），精度1cm；
中距：70cm~400cm左右（根据被测物表面材料决定）；
可调：范围由可调节参数确定，当调节在合适的值时，最远测距700cm左右；
1.2 应用领域
超声波测距模组是为方便学生进行单片机接口方面的学习专门设计的模块，它可以方便的和61板连接，可应用在小距离测距、机器人检测、障碍物检测等方面，可用于车辆倒车雷达以及家居安防系统等应用方案的验证。
1.3 电气参数
超声波传感器谐振频率：40KHz
模组传感器工作电压：4.5V~9V
模组接口电压：4.5V~5.5V
1.4 注意事项
提供给模组的电源必须在4.5V以上，而且尽量保持电源电压的稳定。
模组外接电源接口J3接入的电源不要超过12V。-1.1 profiles three models ranging choice Jumper J1 (short distance, the distance, adjustable from) : Short : about 20cm to 100cm (based on the measured surface materials), the accuracy 1cm; from China : sapling ~ tion about (based on the measured surface materials); adjustable : ranging from adjustable parameters, When appropriate adjustments in the value, about 700cm farthest location; 1.2 Ultrasonic Ranging areas of application modules for the convenience of students in the microcontroller interface specially designed learning modules, it can be convenient and 61 plate connections can be used in small distance range, the robot detection, obstacle detection, and so vehicles can be used to reverse radar and home security systems, applications such as the certification program. 1.3 electric Platform: |
