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. <br />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. <br />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. <br /> <br />The device also can be simultaneously connected to other sensors such as temperature, humidity, smoke detection etc. <br /> <br />Vacker Group supplies various sensors and alert systems for residential and commercial applications
