PIR sensor strictly work on stable 5v but an IR sensor can even work on more than 5v also. As we are using simple 9v battery, it's current rating is low, it doesn't harm IR sensor.
And we have used transistors with PIR to show it's working because PIR don't have built-in LED. IR sensor have an built-in LED to check it's signal status or working. You can use IR sensor with transistor also like we did in PIR video. Working & circuit will be same.
@@Zinbal Okay , thank you sir for replying , my doubt is clear now! And I'll perform that PIR senor's circuit in my ATL class for getting selected there .
@@Zinbal you meant that transistor wasn't necessary to complete that circuit with PIR , we just used to understand the working of transistor . Then why and where should we use transistor?

Thank u 🎉... to make it easy to us😊
Your welcome 🤩
Use full video bro, Thanks
Your welcome
Sir ye tv remote se on hoga kya
❤❤❤❤❤
Very nice👍
Sir home automation
Manual + Bluetooth + wifi
Html se arodinuo project
Soon we will start project wise videos. We will cover it definitely 👍
Sir 1meters tak kam karne wala koi infrared sensor bataiye
Use ultrasonic sensor
why didn't you use a voltage regulator as IR sensore requires 5 volt then? And why not a transister as well as you used in the video of PIR sensor?

Transistor just use for switching of any device, in case of PIR sensor, We are just switching an LED using PIR
