Raspberry PI RF433 transmitter shield

A lot of you are coming to my blog for RF433 with Raspberry PI content (here). This article is a small part of a larger project I have. As part of this project I built a Raspberry Pi shield including an RF433 emitter and receiver. I could sell this shield to some of view if it make interest to you. To make it I selected emitters and receivers to get the best quality / price compromise.  (read my other articles on this topic) I could sell it around 60€ + port.

Update : chek this article for all informations on the shield and buy it !

  1. Hi,

    I’m interested by your offer. Do you also provide software ? I need Oregon decoding capabilities and Chacon / HomeEasy encoding.

    • The objective is mostl to provide hardware with minimum C software to receive RF signals as exemple. The Oregon decoding source can be used with it.

      • Thanks for your reply.

        I tried your code, with a parralax 27982 transceiver, it works fine. But it uses about 30% of cpu, I think this is caused by the poor quality of the power supply. Have you improved the power supply quality on your shield ? Have you some measures of CPU utilization ?

        As an improvement, do you consider to add a MPU on this shield and use GPIO serial for communication.
        An “RFXComm” clone in fact…

        Regards

      • Hello, I did not check that point since a long, so right now, on my system, the CPU load for the process running the RF code + many things is about 2% CPU on the Raspberry PI. What I can tell you is that quality of the receiver is really important, you can watch my test of different receivers and I choose the one that have the best reception coverage + less noise (they are going together). The second point is that the cpu consumption can also be related to the number of decoders you are activating in the interrupt procedure. Less is better for sure, so just activate the one you are using.
        Hope it helps.

  2. Bonjour,

    je pense que je peux me permettre de te laisser un commentaire en français, car il me semble que tu es français et dans tous les cas tu peux ne pas le publier, et échanger directement par email par la suite.

    Ce concept m’intéresse, en fait j’aimerai comprendre comment exploiter tout cela, si tu as quelque détails à donner ? des API ?
    D’autre part est ce que le tarif inclut le Rasp ou simplement l’extension sur le GPIO ?

    Merci pour tes infos.
    Et bravo pour ton boulot !

    • The shield would be GPIO extension (not including the Pi) for detail to use it, you can refer to the Oregon decoding article.

      • Ok thanks for your answer.
        It is quite expensive, evenif I understand that there are many work behind it.
        For example you can found such product for 60€ to 99€ [in different providers] with software/api and so on
        But thanks for all the information you share on your website. 🙂

  3. I would be interested by such a product (as stated, this is an embryonic clone of a RFXCOM).
    Nevertheless, the price tag is a little high. 40 € would probably be a good target: medium price of equivalent extensions for the PI.

  4. Hi,

    I’m interested in the “RF433 transmitter shield”, too. Could you tell me something about the rage of receiving 433Mhz signals? Currently I’m using a cheap 433-Receiver with a poor range of abou 3 meters.

    regards
    Simon
