Arduino ESP8266 ESP32 PHP E-mail (Mailer) Event

---

Email event notifier

---

Event notifier sends emails via php page to your mail in case of critical or important information. The system can be used to send emails for situations:

Motion at night around the PIR sensor - suitable for premises, halls

Heating sensor - suitable for laundry, flats

Temperature sensors - Minus temperature message - Suitable for kits

Humidity, air pressure overheating - suitable for weather stations

Engine Speed ​​Overrun - Hall Magnet Sensor

Overvoltage / current overcurrent

and other measurable variables

The notifiers task is therefore to provide a brief report on the status of the household / room / workplace and to inform about the defaults immediately. Due to the low data rate (a few bytes), it is also possible to use a 3G router with a data rate to connect the ESP or Arduino and to send additional information, such as the current temperature, etc.

Motion sensor for night-time security - silent alarm:

            

Temperature sensor - use in set:

Flooding:

Action on flooding event
