4-Button
Automicro 434MHz Transmitter / Receiver modules with rolling code making it close-to-impossible
to electronically 'crack'. Used in our kit 3180 and
3181 but available here as just the Tx / Rx units
for you to incorporate into your own circuits.
Picture shows the pre-built, aligned and tested keychain transmitter (left) and receiver module (right).
Whether you want to control a garage door or gate, a car and/or home alarm, or perhaps remotely turn lights or anything else on or off, this high-security system is just what you're looking for! 40 metre range (line of sight).
The Tx and Rx modules sold separately.
