Introduction: Home Automation
in this project, we are gone use a lot of things build it from zero to understand the process of IoT internet of things
Step 1: Connect Google Assistant With Raspberry Pi 4
in this step, there is a number of steps you need to follow in order to make your raspberry interface with google assistant
- raspberry pi 4
- USB microphone
- USB speaker
- SDK memory
- raspberry pi imager ( we recommended this software to upload rasbian to SDK memory)
Step 2: LED Switch Using Blynk
- 1- Breadboard
- 3- Relay.
- 4- Connecting wires.
- 5- LED.
- 6- Mobile phone with Google assistant8.
- 7- Blynk app.
- 8- Arduino IDE.
- 9- Wi-Fi router or mobile Hotpot.
- 10- IFTTT web application.
make sure to supply the nodemcu with 3.3v to the 3.3 pin or 5v to VIN pin.
notice that the 3.3 pin has no regulator so you need to use one.
make sure to change the SSID and password to yours.
Step 3: Pir Motion Sensor
we use in this step telegram bot notifications to expand or options it is a safe way as long you have a WIFI connection you will receive notifications
1- Esp 32
2- Pir sensor.
4- Telegram App
bcc to 5v in esp32.
GND to GND
signal to GPIO 27
vin to the positive of the battery
GND to GND of battery.
Step 4: Voltage Detection
Sometimes you need to protect your goods from damage due to interruption
Sudden electrical voltage, for example, butchers and food shops, so we designed a small circuit that gives us notifications in case the voltage is lost.
1- Esp 32
2- Voltage sensor.
3-adaptor (We used adapters to handle low voltages).
GND to GND of esp32
signal to 34 analog pin.
