esp32-cam红外实时监控报警系统(巴发云和邮箱同时推送)

设想-巴发云

我想做一个人体红外传感器发现人体报警,同时给我手机发报警提醒,同时发送图片的设计,找了一些资料,发现巴发云正好可以满足我的要求,结合esp32-cam和人体红外传感器,很好的实现了。代码如下:

/*
 * 2020-07-07
 * QQ交流群:824273231
 * 微信:19092550573
 * 官网https://bemfa.com  
 *
 *此版本需要json库,再arduino IDE 选项栏,点击“工具”-->"管理库"-->搜索arduinojson 第一个库就是,点击安装即可
 *
分辨率默认配置:config.frame_size = FRAMESIZE_UXGA;
其他配置:
FRAMESIZE_UXGA (1600 x 1200)
FRAMESIZE_QVGA (320 x 240)
FRAMESIZE_CIF (352 x 288)
FRAMESIZE_VGA (640 x 480)
FRAMESIZE_SVGA (800 x 600)
FRAMESIZE_XGA (1024 x 768)
FRAMESIZE_SXGA (1280 x 1024)

config.jpeg_quality = 10;(10-63)越小照片质量最好
数字越小表示质量越高,但是,如果图像质量的数字过低,尤其是在高分辨率时,可能会导致ESP32-CAM崩溃

*支持发布订阅模式,当图片上传时,订阅端会自动获取图片url地址,可做图片识别,人脸识别,图像分析

转折-照片数量限制

但是问题也来了,可能是图库成本太高的原因,巴发云之能免费存储100张图片,超过了就要开会员,而且,这100张是永久的一次性的,无法删除,本人最近经济太拮据了,已经坐吃山空,也想支持以下这么好的云平台,但无奈那个中羞涩。找了很多地方也没有解决方法,于是我把图片的转发希望转到了其他的方法,直到我看到有文章说可以通过邮件的附件的方式传给我自己的邮箱,于是开始搞起。这是巴发云上使用esp8266上传人体红外传感器到微信发送报警的代码,这个报警的次数是没有限制的,但是只能文字提醒。没有图片。

避开巴发云照片限制

我的想法是移植到的esp32-cam板子上,这个 <ESP8266WiFi.h>头文件要改成<6WiFi.h>,但是我把doHttpStick()微信消息推送函数一直到esp32-cam板子上的时候,发现并不能运行,<ESP8266HTTPClient.h>头文件已经改成<HTTPClient.h>,提示http未定义错误,我才发现, http.begin(client,ApiUrl); 之前没有对http进行定义,所以我加了一句句代码, HTTPClient http;终于可以了,哇咔咔。以下代码顺利编译通过了,

邮箱的坑

但是一开始我使用的是qq邮箱,找了一大顿方法和qq邮箱的设置,获取到了授权码,但是通过串口工具,一直提示鉴权被拒,于是转变思路,换成163邮箱,终于实现了。
