Story

In this project every time a bell switch at door is pressed, an alarm will be generated and an email will be sent to a specific person. RF modules are 433 MHz RF transmitter and receiver modules. The transmitter draws no power when transmitting logic zero while fully suppressing the carrier frequency thus consuming significantly low power in battery operation. When logic one is sent carrier is fully on to about 4.5mA with a 3volts power supply. The data is sent serially from the transmitter which is received by the tuned receiver. Transmitter and the receiver are duly interfaced to two micro controllers for data transfer.

In order to send e-mails from ESP8266 Module, you need to follow the SMTP protocol. Hence, anSMTP Server is required to send the e-mails and the ESP8266 will act as an SMTP Client. In this project we will be using SMTP2GO server.

Code

Sending the “DATA” followed by the Message body of the e-mail.

client.println(“DATA”);
client.println(“To: receiver@gmail.com”);
client.println(“From: sender@gmail.com”);
client.println(“Subject: ESP8266 test e-mail\r\n”);
client.println(“This is is a test e-mail sent from ESP8266.\n”); client.println(“Second line of the test e-mail.”);
stage 8: Finally, terminate the mail with “.” and send the quit command. client.println(“.”);
client.println(“QUIT”);
