Pin 7 is not for an output of IC1. You can use any IR sensor available in the market for TV remote receiver.

I Assume pin 4 on IC2b is to ground. Actually I have seen the same circuit with the different connections. Would you please give me a detailed explanation of how the receiver works ie from the photo diode to the IC2b pin 7. Pow er supply to the rf sensor. You may also like: Can you please let me know how to make 5VDC power supply without ba1600.

This is my first time constructing a circuit and I do have alot of things which I have not learnt to construct in college. Hi Sujit you should get between 30 to kHz from pot one end to other. Hello can any one tell me what is the value of the IR diode that is required for this circuit?


To answer your first question. When you power-on the circuit after assembling all the components including the CFL, the CFL will glow for 10 seconds, turn off for 30 seconds, glow for 10 seconds and then turn off.

Hi Anjum please go ahead and give further feed back. If the supply you have is greater than 12V, use a regulator like to bring it down to 12V. Where do you give the power supply to the transmitter?

The reciever however is construced as above yet the output never changes when there is movment between the diode and phototransister. Thanks for yor kind reply.

Insulate the track side of the PCB using an insulating foam and glue to the base. It adjusts the amount of gain for the op amp.

Hi bs160, can anyone please let me know the connections of pin no. If there is no person in front of the fan will stop after 30 seconds automaticaly. Anjum — Click on this senosr to know more http: When any movement is detected, around 3. Sorry for not responding sooner. I know how to make it but how important is it? Please reply with any info Kind Regards Rich. Leave a Reply Cancel reply Your email address will not be published. I am doing a project at my local college and was hoping to get the components list of this circuit.


In this circuit it is calculated to be 5KHz. This can sometimes be bypassed by using an op amp that works off a single supply aensor.

Hi, Can someone that constructed this circuit and made it work get in contact with me. And I only have 4 days to built. A replacement for the LM is: Hi iam also working for this cct as my projectbut i dont understand that how 50k n k potentiometer workwhy we r using it?

Please enlighten me on how to connect it as my current way — by bringing two 12V supplies to parallel does not seem to work. Why is it that when you walks into the field of view of the PIR sensor and stands their the piezo alarm stops ringing.

Hi Anjum you can use 9 volt battery for the transmitter without any modification, use only alkaline for longer life. Below is the Link: Hi all, can any one let me How to change LM The 12V DC power supply required for the motion detector and the relay driver is derived from V, 50Hz mains using a transformerless circuit as shown below. There is the problem in reciever circuit. Do not forget the freewheeling diode for the relay.
