RFID Prop Trigger with Relay

In stock
Consists of a small key fob that is totally self contained (no moving parts or batteries) and a proximity sensor and associated receiver circuit box. When the key fob is brought within 3 inches of the sensor, the unique data encoded in the key fob is transferred to the sensor-receiver, activating whatever device (controller, relay, solenoid, light, locks, etc.) that you have connected to the receiver.

    2. Make sure the new keys you are using are 125kHZ.
    3. Remove the master key from the metal tin.
    4. Hold the master key next to the antenna for a few seconds (the antenna is the domed black plastic piece. The top of the dome is where it has the best sensing capabilities).
    5. Remove the master key and place your new key near the antenna. Leave it there for 5 seconds.
    6. Pull the key away and then bring it back in range of the antenna. The relay should click.

    How do you encode new fobs with with master for your RFID?

    Each RFID trigger comes with a Master Key (it is enclosed in a metal tin). To flash a new key, simply open the tin and hold the new key close to the Master Key for a few seconds. The new key will now be configured to work with that RFID sensor.

    Will the RFID trigger be able to trigger from the back side of a mirror if the receiver is behind the glass of a mirror and the tag is on the front side of the mirror?

    The RFID does not trigger through mirrors that have metal backs. It does not work through 22ga sheet metal. It barely works through aluminum foil. If you have just a straight up mirror with no metal backing then it will work.

    Can you connect the RFID trigger to the PicoBoo? If so, how?

    Yes, “C” and “NO” from the RFID to the PicoBoo “IN” and “-“
