LR1200E4 · 905 nm Laser Rangefinder Module

LR1200E4 Arduino 库与示例程序

erdi-lrf-drivers 里的 Arduino 库解析 LR1200E4 的帧(8 B / 2 B,115200 波特率),返回以 m 为单位的距离。请用硬件串口;这个速率下 SoftwareSerial 不可靠。

接线

LR1200E4 TX → Arduino RX1,RX → TX1,GND → GND,供电 3.3–5 V。接口电平:UART-TTL;接 5 V 板子前先确认电平。

示例程序

#include <ErdiLRF.h>
ERDI_LR1200E4 lrf(Serial1);   // LR1200E4

void setup() {
  Serial.begin(115200);
  Serial1.begin(115200);
  lrf.begin();
}

void loop() {
  if (lrf.readSingle()) {
    Serial.println(lrf.distanceMeters());
  }
  delay(100);
}
