我不能同时使用水流量传感器和 GSM(SIM900)。一旦我同时使用两者,GSM 将完全无法工作。我尝试了很多方法来解决它,但仍然没有成功。希望大家能给我一些帮助。

我遇到了同样的问题。解决方案是停止运行时间 2 中断以发送消息。
您的代码的编辑:
void sendSMS2()
{
cli();
gsm_condition_1 = HIGH;
SIM900.print("AT+CMGF=1\r"); //AT command to send SMS message
delay(100);
SIM900.println("AT + CMGS = \"" + destinationNumber +"\"");
delay(100);
SIM900.println(outMessage2); //message to send
delay(100);
SIM900.println((char)26); //End AT command with a^Z, ASCII code 26 or ctrl+z
delay(100);
sei();
}
问题是传感器只能使用中断读取,但当中断处于事件状态时,您的 sim900 将无法运行。所以你必须暂时禁用中断然后继续。此外,SIM900.print("AT+CMGF=1\r");
应该处于无效循环中。
最后一个问题是您的 sim 900 不会发送整数。所以你必须将它作为一个字符串发送。请按照以下示例进行操作:http://microembarcado.blogspot.com.au/p/wr-bridge-send-sms-with-temperature.html
我坐了大约 4 个小时才弄明白。 希望这会让您的事情变得简单一些。
