Assignment 1 - Wireless Sensor Node
a) Develop a Sensor Circuit using commodity components
b) Design a wireless sensor node using commodity wireless modules
Assignment 1(a) -Sensor Circuit
The first part of the assignment is to design a prototype of home security system with passive proximity sensor, light sensor, temperature sensor and examine its performance.
Note: You have to demonstrate the working of the circuit.
Students are to design the security system with the proximity, light and temperature sensors. All sensors should be incorporated in one big circuit and if any sensor senses an intruder then it should trigger an alarm. The alarm could be flashing of LED or a speaker in the prototype circuit. You should have a schematic of your circuit during demonstration.
Assignment 1(b) -Wireless Sensor Node
Students are to design a wireless sensor node, which can wirelessly transfer the sensor information to a remote location. The circuit developed in sensor assignment 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 working of your assignment. You have to use HT12E encoder, HT12D decoder, 433 MHz Transmitter and Receiver.
