MADLAB ELECTRONIC KIT - E-LOCK

The E-Lock is an electronic combination lock that is controlled by your mobile phone. The E-Lock picks up, using the onboard microphone, the DTMF tones generated when the keypad of a mobilel phone is pressed. When the correct combination of keys has been pressed, the E-Lock's 1 amp integrated relay is activated. The relay can be connected to a solenoid (not supplied), or other device, controlling the lock on a door or enclosure.
