Hello Every one
I have a maliday tpms sensor which send the rf signal of 433mhz it has the modulation of FSK , I was Facing the problem with the receiver, the receiver which i have used was the hc-12 it was unable to catch any of the rf signals I wanted to know which receiver will be appropriate to use to receive FSK modulation 433mhz transmittera.
Just saying that something uses FSK modulation does not give enough information. Does the carrier shift up in frequency or down in frequency? How many start bits are sent before data bits? How many stop bits are sent at then end of each character? There is no universal standard. And then they may say FSK when they actually use AFSK, which is shifting an audio frequency that modulates the carrier.
Search the web to see if someone has already come up with a way to receive data from the "maliday tpms sensor".
If not, it will take a fair amount of technical expertise to reverse engineer the signal and built a receiver.
How do You verify that the transmitter runs as expected?
Its a 32 bits data not any audio
That sensor has sent the data through 433mhz FSK modulation transmitter, Since its Sending the data that data I want to catch I was able to Catch it through normal receiver but was unable to catch complete packag hence i need a FSK modulated 433mhz receiver
See post/reply #3.
Sir I have placed a led which detects the 433mhz rf signals through normal rf receiver which was the ASK modulation
Did't got u
No, I guess not. Have fun, though!
Please link to a data sheet on that receiver. It likely will turn the LED on when ANY signal is received.
Take your transmitting and receiving equipment and visit a local amateur radio group for help.

Perhaps This will help the OP with possible parameters for a TPMS:
Sir I know I need these specifications but the thing is i am not getting a proper receiver for it
Not much an Arduino can do about that.
