Design a prototype of home security system with passive proximity sensor, light sensor, temperature sensor and examine its performance. Following this, you’ll also have to design a wireless sensor node, which can wirelessly transfer the sensor information to a remote location. The sensor circuit developed above will be used with a 433 MHz transceiver module. The receiver module of wireless sensor node should turn on an LED in order to demonstrate its working. You have to use HT12E encoder, HT12D decoder, 433 MHz Transmitter and Receiver.
The question belongs to Electronics Engineering and it discusses about designing a prototype security system with passive proximity sensor, light sensor and temperature sensor and designing a wireless sensor node which can wirelessly transfer the sensor information to a remote location.
