This is a water leakage sensor which can be connected to the phone call and SMS alert system by Vacker. This is now connected to a 20 meter sensor cable which has to be laid out on the floor of the area to be monitored.
I am demonstrating this by touching a drop of water onto the sensor cable. There are audible and visual alarms on the sensor which are now activated.
Now the sensor has also activated the auto dialer unit which has a SIM card inserted into it. The dialer unit will make phone calls and SMS to 4 operators. The phone call is now received by the first operator. Upon attending the call a voice message is delivered indicating the location and nature of the fault.

The device also can be simultaneously connected to other sensors such as temperature, humidity, smoke detection etc.
