Passive Infra-Red (PIR) will detect movement in room and activate alarm. PIC microcontroller continuously monitors the current values of sensors and sends data to receiver wirelessly via Zigbee module. An information is displayed in the form of graph on TFT LCD. The values of all these sensors are also pushed into the cloud storage continuously via Wi-Fi module and can be monitored on Android app from remote location. In case of any fault or hazard, the STM microcontroller on receiver will activate an alarm and send SMS via GSM. Languages -          English, Urdu, German (Beginner)
