WeMosD1+PIR+Android的小场景制作

最近在做一个有趣的小场景功能，其实已经有成熟产品，但是考虑到没法实现场景扩展，所以自己开始动手做。

场景描述：玄关人体感应，有人进门，致欢迎词，有人离开，致欢送词。

硬件设备：WeMOS D1 + PIR 【HC-SR501 】 + Android手机

数据流：

从WeMOS D1开始

WeMos D1主要是是作为TCPClient,将接收到的PIR信息推送给android系统，并接收反馈信息

/* This sketch establishes a TCP connection to a "quote of the day" service. It sends a "hello" message, and then prints received data. */ #include <ESP8266WiFi.h> #ifndef STASSID #define STASSID "your-ssid" #define STAPSK "your-password" #endif const char* ssid = STASSID; const char* password = STAPSK; const char* host = "djxmmx.net"; const uint16_t port = 17; void setup() { Serial.begin(115200); // We start by connecting to a WiFi network Serial.println(); Serial.println(); Serial.print("Connecting to "); Serial.println(ssid); /* Explicitly set the ESP8266 to be a WiFi-client, otherwise, it by default, would try to act as both a client and an access-point and could cause network-issues with your other WiFi-devices on your WiFi-network. */ WiFi.mode(WIFI_STA); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); } Serial.println(""); Serial.println("WiFi connected"); Serial.println("IP address: "); Serial.println(WiFi.localIP()); } void loop() { static bool wait = false; Serial.print("connecting to "); Serial.print(host); Serial.print(':'); Serial.println(port); // Use WiFiClient class to create TCP connections WiFiClient client; if (!client.connect(host, port)) { Serial.println("connection failed"); delay(5000); return; } // This will send a string to the server Serial.println("sending data to server"); if (client.connected()) { client.println("hello from ESP8266"); } // wait for data to be available unsigned long timeout = millis(); while (client.available() == 0) { if (millis() - timeout > 5000) { Serial.println(">>> Client Timeout !"); client.stop(); delay(60000); return; } } // Read all the lines of the reply from server and print them to Serial Serial.println("receiving from remote server"); // not testing 'client.connected()' since we do not need to send data here while (client.available()) { char ch = static_cast<char>(client.read()); Serial.print(ch); } // Close the connection Serial.println(); Serial.println("closing connection"); client.stop(); if (wait) { delay(300000); // execute once every 5 minutes, don't flood remote service } wait = true; }

PIR功能的开发测试链接：

在 Arduino 上使用 HC-SR501 人体热释电（PIR）传感器 – Arduino 实验室 (nxez )

其中的有些代码还是要调整的：

int pirPin = D5; // PIR传感器连接的引脚 void setup() { pinMode(pirPin, INPUT); // 将PIR传感器引脚设置为输入模式 pinMode(LED_BUILTIN, OUTPUT); Serial.begin(115200); // 初始化串口通信 } void loop() { int pirValue = digitalRead(pirPin); // 读取PIR传感器的值 if (pirValue == HIGH) { // 如果检测到运动 digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW delay(1000); Serial.println("Motion detected!"); // 在串口打印消息 delay(1000); // 延迟1秒 } else { digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW delay(1000); } }

通过Android系统，搭建TCPServer接收 WeMos发送的PIR的测试信息.

Android功能待更新...
