How does the module operate?

Mode 1 Mode 2 Modes 3 Mode 4 Mode 5 Mode 6 Mode 7 Mode 8

By adding the supplied jumpers to pins on the circuit board you can have 8 different modes of operation. Disconnect the power supply  before placing the jumpers on the pins.

You need to supply an old mobile phone/cell phone. The backlight on the screen must stay illuminated for as long as the phone is ringing. We call this the receiver phone or Rx. To turn the socket ON or OFF you make a call from any type of phone, mobile/cell phone or landline or even web phone. We call this phone the transmitter phone or Tx. You need to find out how long the back light stays on, on the receiver phone Rx, for a given number of rings from your transmitter phone Tx.

The critical thing to find out is how many rings of Tx will keep the backlight on Rx, on for 20 seconds or more. For example, when I ring the my old phone which is attached to the Module, it takes 5 rings to keep the back light on for just over 20 seconds. Remember that the backlight will probably stay on for a while after you terminate the call. You will need to test this yourself because your phone may be different. With most phones two rings from the transmitter phone will turn the back light on for under 20 seconds and seven or eight rings will keep the backlight on for longer than 20 seconds. 

The Module is attached to your old mobile phone by means of the LDR and black tape (see picture at top of page). When your mobile receives a call the backlight comes on for a period of time. This is sensed by a light dependent resistor (LDR) which activates the Sockets depending on the amount of time the backlight stays lit.

Mode 1 is the most complex but is still easy to operate. It is the mode where you can operate the Sockets independently of each other.

Mode 2 turns ON both Sockets with a short number of rings and OFF with a long number of rings.

Modes 3 to 7 operate like a countdown timer. If the times mentioned don't suit your particular application please let us know and we will adjust the countdown times to match your needs.

Modes 3 turns both Sockets on for 5 seconds.

Mode 4 turns both Sockets ON for 30 seconds

Mode 5 turns both Sockets for 60 seconds.

Mode 6 turns on both Sockets for 30 minutes.

Mode 7 turns on both Sockets for 60 minutes.

Mode 8 toggles both Sockets on and off.

Please follow the links for a detailed description of each mode. As you can see, Modes 3 to 7 operate like a countdown timer turning the Socket OFF automatically when the time runs out. Mode 8 toggles the pairs of Sockets ON and OFF with each alternate phone call.
