HC-SR501 Motion Sensor usually known as the PIR sensor isused in many kinds of Security Alarm Systems and MotionDetector systems. Instead of emitting infrared signals, it absorbs IR signals and that’s why it is called PIR (Passive Infrared) Sensor. Every object emits heat in the form of IR rays, so whenever the PIR sensor detects any change in heat, its output pin becomes HIGH. The key components of the PIR sensor are the Pyroelectric sensor and Motion Detector IC BISS0001.

BISS0001 IC takes the data from the sensor and measures the output pin HIGH or LOW accordingly.

We used a PIR sensor with NodeMCU to build an IoT Motion Detector System which not only sends an email whenever it detects some motion but also shows it on a webpage with time and date.

Components Required

  1. NodeMCU(ESP8266)
  2. Motion Sensor HC-SR501 (PIR Sensor)
  3. Buzzer
  4. Jumper Wires

Circuit Diagram

The circuit diagram of the IoT
Motion Sensor Circuit is shown below:

The circuit is very simple as we are only connecting the PIR sensor and buzzer with NodeMCU. VCC and GND pins of PIR

Sensor is connected to VIN and GND of NodeMCU, while the Data pin is connected to D1 (GPIO 5) pin of NodeMCU. The positive and GND pins of the buzzer are connected to D5 (GPIO 14) and GND of NodeMCU respectively.

IFTTT Setup for IoT Motion Detector IFTTT (If This Then That) is a web-based service by which we can create chains of conditional statements, called applets. Using these applets, we can send Emails, Twitter, Facebook noti cations, SMS, etc.
