esp32-cam infrared real-time monitoring and alarm system
Vision-Ba Fayun
I want to make a human body infrared sensor that detects human body alarm, and at the same time send an alarm reminder to my mobile phone, and at the same time send the design of the picture, I found some information, and found that Bafayun can meet my requirements, combined with esp32-cam and human body infrared sensor, Well done. code show as below:

*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

Twist - photo limit
But there is also a problem. It may be because the cost of the library is too high. Bafayun can store 100 pictures for free. If it exceeds, you need to open a membership. Moreover, these 100 pictures are permanent and one-time and cannot be deleted. I recently The economy is too tight, and I have already sat on the mountain, and I want to support such a good cloud platform as below, but I am shy about it. I searched many places and found no solution, so I turned the forwarding of the pictures to other methods, until I saw an article saying that it could be sent to my own mailbox through the attachment of the email, so I started to do it. This is the code for uploading the human body infrared sensor to WeChat to send an alarm on Bafa Cloud using esp8266. There is no limit to the number of alarms, but only text reminders. No image.

Avoid the photo restrictions of Bafa Cloud
My idea is to transplant it to the esp32-cam board. The <ESP8266WiFi.h> header file needs to be changed to <6WiFi.h>, but when I put the doHttpStick() WeChat message push function on the esp32-cam board, I found that it couldn’t run, the header file of <ESP8266HTTPClient.h> has been changed to <HTTPClient.h>, it prompts http undefined error, I just found out that http.begin(client,ApiUrl); didn’t define http before, so I added After a sentence of code, HTTPClient http; finally works, wow. The following code compiles successfully,

mailbox pit
But at the beginning, I used the qq mailbox. I found a method and the setting of the qq mailbox. I got the authorization code, but through the serial port tool, I kept saying that the authentication was rejected, so I changed my thinking and changed to 163 mailboxes, and finally realized up.
At the same time, my Bafayun WeChat was also alerted to the police, although there was no picture displayed.
