Intruder detector using a Reed Switch DIY Kit

Description

In this project, we will be making a simple intrusion detection or alarm system using Reed Switch

In this quick tutorial we are going to learn how to send emails and push notifications from the WiFi ESP8266 module, or any other IoT device, using Blynk Email and Push Notification APIs. For this demonstration, we are going to build a simple thermometer project and then set up temperature Alarm points. Whenever the alarms will trigger, an email and a push notification will be sent.

The Reed switch/Door Sensor is a simple contact that closes when a magnet is brought close to it. Thanks to this effect we can sense when doors or windows are opened or closed.
