This is the code for the Home Automation project. Here we have connected ESP32 with various sensors & actuators like DHT22, LDR Sensor, PIR Sensor, Ultrasonic Sensor, LED, Relays & Buzzer.

 

Also, the project can be then connected to the Blynk App/Web-Dashboard to check the status/values from sensors and set a notification for Alert. Find the Project circuit diagram here - Link

 

Project working -

 

Part 1: DHT22 sensor will sense the room temperature continuously and in the code logic we have defined that if the temperature is above 30 Degrees Celcius then the room is a little warm and 1 LED glows to indicate the same, on the other hand, if the temperature is above 60 then buzzer turns ON as an alarm plus a push notification is sent to the Blynk App.

 

Part 2: PIR Sensor & LDR Sensor senses human presence & light intensity and based on that send a signal to the relay/s to turn ON/OFF  the Bulb, Fan connected to the relay/s.

 

Part 3: The Ultrasonic sensor detects human presence (if in 50cms range of the door) and based on that opens & closes the door(here for the prototype project we rotate the servo motor)

 

Part 4: Everything happening is sent to the Blynk Cloud and then displayed on Blynk Web Dashboard or Blynk Mobile App.
