Great 433MHz transmitters and receivers
First class......Arrived on the day as promised. Well packaged and worked straight out of the box. Have 2 transmitters controlling TV and HiFi with Amazon Echo and ESP8266. Boards are well marked and well finished. Solder work is good!

    I haven't tested them all, but so far so good. Combined with an Arduino I have been able to decode and send signals for turning remote control sockets on and off, and to decode signals sent from a remote temperature sensor (bought from Thermopro on Amazon). With a 1/4 wave antenna added (17.3cm piece of copper wire) the transmit range seems pretty good, I can switch sockets on and off on the next floor up.
    These are not plug and play, you need to interface them with some kind of microcontoller to transmit and receive the signal encoding you need. Ideal for Arduino/NodeMCU projects.

    Does the job - no data sheet though, but it's the same as many other 433MHz transmitters out there.

    Packaged in a static proof bag.

    I'm using these to control remote sockets, and they work fine :)

    I bought these to use with my Raspberry Pi 3 after I was having no luck with getting the transmitters to work with another brand after many hours of attempting (I'm new to this kind of thing so I thought I was doing something wrong). Needless to say that these worked fine with zero issues and I can finally get my home automation project started.

    3.0 out of 5 stars waste of money
    Reviewed in the United Kingdom on 2 May 2022
    Verified Purchase
    All the transmitters had solder flux residue. The receivers were clean.
    One transmitter failed to oscillate at voltages below 4.5v.
    One receiver failed to receive a good transmitter even at a range of a few centimeters.
    The other transmitters and receivers were all compatible, but the range is <2m even with spring antennas on both transmitter and receiver. A waste of money

    Bought these to build a tester for car remote key fobs after struggling to diagnose why a car wouldn't respond to a new fob. Only tested the receiver as a result but with a 5v poser supply from an Arduino you can see the data stream from the remote confirming if it's transmitting or not.

    5.0 out of 5 stars Funktioniert Gut - noch besser mit zusätzlicher Antenne
    Reviewed in Germany on 29 August 2017
    Verified Purchase
    Sender wie auch Empfänger funktionieren am Arduino UNO, NANO und auch an kompatibelen Boards gut. Die Sende- und Empfangsleistung wird noch entscheident verbessert, wenn man eine Antenne anlötet. Diese ist leider nicht im Lieferumfang enthalten, ist aber auch so korrekt beschrieben. Insgesamt ist das Produkt mit diesem Umfang und zu diesem Preis empfehlenswert.

    5.0 out of 5 stars Perfetti per l'hobbystica !
    Reviewed in Italy on 12 September 2016
    Verified Purchase
    Funzionano e fanno il loro dovere. Su 6 pezzi (3 ricevitori, 3 trasmettitori) nessuno difettato.
    Sono perfetti per chi vuole imparare a usare le trasmissioni radio in AM. Li consiglio per creare una rete di sensori o per rendere una casa domotica.
    Ovviamente non sono moduli che offrono stabilità e sensitività eccelse, nel caso in cui vengano usati per trasmissioni particolari consiglio di irrobustire la trasmissione utilizzando un protocollo.
    Io li sto usando per la trasmissione e la ricezione dei radiocomandi per cancelli a 433,92 MHz con arduino uno e libreria RCswitch.
    Consiglio di aggiungere un antenna esterna. Io ho utilizzato un doppino telefonico.
    Inoltre ho notato che i ricevitori soffrono nel caso l'alimentazione sia sporca, per esempio alimentandoli direttamente dalla usb del pc. Consiglio di aggiungere un condensatore esterno in parallelo ai pin di alimentazione.

    4.0 out of 5 stars Sehr gute Sender/Empfänger, aber nur bei richtiger Spannung
    Reviewed in Germany on 7 December 2018
    Verified Purchase
    Die 433MHz Sender und Empfänger funktionieren sehr gut und die Reichweite ist ebenfalls sehr gut, falls man sie mit der richtigen Spannung betreibt.
    In der Beschreibung steht zwar drin, dass man sie mit 3.5V bis 12V betreiben könnte, aber das hat bei mir nicht wirklich funktioniert.
    Ich habs zuerst mit etwa 3.75V probiert (wegen einem zu langen USB-Kabel...). Damit funktioniert der Empfänger zwar, aber nur auf einer Reichweite von etwa 2m.
    Mit höheren Spannungen (von über 6V) funktionierte der Empfänger bei mir ebenfalls nicht mehr richtig (ist zwar nicht kaput gegangen aber hat auch keine Signale mehr Empfangen.

    Bei einer Spannung von etwa 4.9V bis 5.7V funktioniert der Empfänger aber letztlich sehr gut.
    Die Reichweite habe ich nicht komplett ausprobiert, aber es hat gereicht um durch das ganze Haus zu senden (ca 10m durch Wände, ...)

    Einige Tipps zum Einsatz:
    - In Verbindung mit einem Arduino funktionieren die Module sehr gut, aber man sollte darauf achten, dass aus dem 5V ausgang des Arduino auch 5V rauskommen (was nicht passiert wenn man ihn über USB nur mit 3.7V versorgt)
    - USB-Kabel haben einen höheren Wiederstand als ich dachte...
    - Wenn man den Arduino über z.B. eine 9V Batterie betreibt, die am VIN oder RAW pin angeschlossen ist funktionieren die Module sehr gut

    Fazit:
    Sehr gute Sende-/Empfänger-Module, aber auf die richtige Spannung achten.

    Venditore cordiale e gentile, spedizione velocissima. Se vi servono dei moduli RF in tempo immediato allora fanno al caso vostro. Li ho comprati per comandare una macchinina a distanza, purtroppo la libreria che utilizza questo modulo va in conflitto con moltissime librerie di Arduino (parlo di Arduino UNO, nel mio caso). Quindi se siete intenzionati ad acquistare questi moduli per comandare a distanza delle macchinine o un qualsiasi apparecchio che utilizza la libreria Servo.h oppure Wire.h non lo consiglierei a pieno, si possono trovare delle soluzioni alternative ovviamente però richiederà più impegno e tempo. Comunque svolgono il loro lavoro anche se consiglio vivamente di saldarci un antenna (è disponibile un foro su entrambi i moduli in cui è possibile saldare l'antenna).

    5.0 out of 5 stars erfüllt absolut seinen Zweck
    Reviewed in Germany on 7 April 2017

    Ein sehr günstiges Pack, welches hier einwandfrei funktioniert.Sollte mal ein Teil ausfallen, hat man gleich noch Ersatz parat. Sehr gut!

    Wird hier benutzt, um RSL-Funkschalter von Conrad via Raspberry/pilight anzusprechen (Markise + Standardschalter). Dies läuft sehr zuverlässig.

    Tipp für Nutzer mit einem ähnlichen Setup: Ihr könnt das Pairing ohne die dazugehörige Fernbedienung vornehmen: Sender am Raspberry anschließen, pilight einrichten und Service starten. Danach dann folgenden send-Befehl über die Konsole starten (=Dauer-Sendebetrieb):

    while true; do pilight-send -p conrad_rsl_switch -u 1 -i 1 -t ; done

    Werte für -u/-i je nach Bedarf anpassen (am besten pilight-Doku lesen).

    Danach dann das Pairing am RSL-Schalter starten. Dieser sollte bei korrekter Funktionalität das Sendesignal erkennen und sich koppeln. Ab dem Moment kann der Raspberry den Schalter via:

    pilight-send -p conrad_rsl_switch -u 1 -i 1 -t
    bzw.
    pilight-send -p conrad_rsl_switch -u 1 -i 1 -f

    ein-/ausschalten.

    Viel Erfolg!
