How to turn on / off anything at a specific time with Arduino
In this tutorial, we will learn how to turn on / off anything at a specific time. For this we will use DS1302 RTC module and Relay module.

For most of our Arduino projects that require to detect when an individual has left or entered the world , or has approached, HC-SR501 PIR sensors are an excellent choice. they’re low power and low cost, pretty rugged, have a good lens range, easy to interface with and are insanely popular among hobbyists.
HC-SR501 PIR sensor has three output pins VCC, Output and Ground. it’s a built-in transformer so it are often powered by any DC voltage from 4.5 to 12 volts, typically 5V is employed . aside from this, there are a few options you’ve got together with your PIR.
