How to use 433 and 315MHz pair | RF | Wireless | Remote Control Systems | Home Automation 

Thank you 🙌

Thank you for your support

Im sorry i didn't understand your little joke, anyways thanks for the comment

Thank you!!! contact me via email, I'll try my best to help you out. email: kidi1086js@gmail.com

What is your email ID. I am not on Instagram.

Thanks for your comment, i already have a video in making about sending data with these rf modules, and that data can be anything, like water level information or anything you want, so subscribe and dont forget to press the notification bell so you wont miss that video!

@@jitulex thañks, i already have subscribed. Plz include showing data on lcd

that is due to the bias on the data pin, if you connect an digital encoder and decoder ic to the setup, it will be able to detect this high and low as digital signals, try that out, i have a seperate video about it so do give it a try, if the problem still persists, do leave a comment

There is no resistor connected between data and ground in any of the circuit

Apparently these modules are not very reliable, the connection between them is very unstable hence i dont use them much in my projects, but if you wish to you can try to use it as a 315mhz module by not connecting more components to the board, the reason why this board has missing components is because these modules were initially designed for 433mhz only but i guess to fill the market, people also came out with the 315mhz option but just modifying the oscillator section of the modules and changing its frequency

@@jitulex yea I just switched to a better module. Nrf24L01 seems to work but I haven’t tested it yet

It works fine just requires 2 seperate microcontrollers on each end, transmitter as well as receiver hence increasing the cost dramatically compared to the 433mhz as well as these modules work on spi and coding for them to work properly increases complexity.

Fast

The connection between the tx and rx modules possibly would be bad or non existent.

Try replacing the tx and rx modules

Or double check your connections

K thanks

Yes you can but you have to make sure that the sensor is working in the active low state, which means when the sensor detects something then it will give an 0 at the output

Thank you for your suggestion!

Yes you can connect the output to an motor driver ic like the l293d and connect the motor to the ic

Is it work without l293d ic

Yes you can use the output to turn on a transistor with a resistor on its base

I not understand

Contact me on 6387419212 WhatsApp I'll assist you

Yes you can, i have a seperate video showing how to

What do you mean? Can you be a little elaborative? Which circuit do you need to be designed?

@@jitulexSir very first thing thanks for the reply , a circuit with no transmitter and receiver module used separately , for example if you see in simple Remote Control circuit used in RC toys , to control the motors ( servo motor , dc motor etc ) .There's no transmitter and receiver module's used in the RC toys. , no transmitter module in the transmitter or no receiver module in the receiver side . So any circuit Explaining how the signal is transmitted from transmitter to receiver to control the motors in toy. There's no transmitter and receiver module's used in the RC toys.

Sir I don't want to disturb you , maybe I am able to explain you what I want , but still trying my best , can you make the same circuit of the transmitter and receiver module's you are using ,on the bread board , do you have the circuit diagram of module's , just wanted to know working of the circuit , of the transmitter and receiver module's , how the signal is transmitted from transmitter to receiver to control the motors or leds

I don't know much about but the transmission and reception in rc toys use same principle. The input signal is multiplexed into higher frequencies using a set of transistors and crystal oscillators and then it is fed to a antenna and is received at receiver and Demultiplexed. Making a rf circuit with higher range is not preferable as it needs license. Hence you can use the modules with license. You can even google how rf circuit works for precise and better information.

Are you talking about the HT12E and HT12D system?, I can presume that because you mentioned switch, so I have an separate video on that and how it works, check that out, check that all your connections are right according to what I showed in the video, then if it still doesn't work, leave a comment on that video, the link is: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-jhAmtzrcUrg.html

@@jitulex nhi yhi wala hai system bilkul jo aapne kiya vhi kiya maine bhe prr mera bss ho ne rha hai yea problem krra hai

@@navneetsaini7442 Contact me on Instagram DM id is @jitulex

Sure Please contact me on @jitulexjitendradsingh@gmail.com and i will help you out

Yes

Uspar bhi ek video bana dijiye please

Pls make a rc car using this kit

When properly paired up with the correct antenna, iska range 300 metres tak hai

300 metres as in open space

Thank you for the feedback but can you elaborate a little on it?

Can you please explain your suggestion?

@@jitulex if you can't see clearly what you say?

We say either increase the resolution or fix the lighting, we never say to shoot without proper lighting or shoot in dark.
