Motion Sensor

It's Arduino code for NodeMCU ESP8266 client with a motion sensor. You can use any model you want.

How-to

1. Create your env file from env.cpp.example :

    #include <Arduino.h>
    #include "env.h"
   
    const char* wifi_ssid = "";
    const char* wifi_password = "";
   
    const String alert_url = "";
    const uint8_t alert_url_fingerprint[20] = {};

2. Set proper alert URL with it's SHA1 fingerprint. For example, you can use Telegram Bot API.

3. Upload the project to your device.

Work process

1. Connect to WiFi network
2. Detect motion
   1. Count HIGH value from digital input pin with 10ms delay
   2. If count > 10 we have a real motion
3. Send POST request to provided URL
4. Try again if response != 200,301
