Hardware components and setup

The following is a list of the hardware components and the quantity of each needed to build the smart kitchen project:

Photons (2)
Li-Po batteries (2)
3-6V DC power supply (2)
RFID Reader module RFID-RC522 (1)
RFID tags (6)
Passive infrared (PIR) motion sensors (3)
Jumper wires (20)
Breadboards (2)

We will describe some of these components in detail, and explain the function they perform.

RFID reader module RC522-RFID and RFID tags

Radio frequency identification (RFID) is a Near Field Communication (NFC) technology, where two devices can transfer data between them using radio waves when they are near each other:

Figure 2: MIFARE RC522 RFID reader module (left) and RFID tag (right)

We use the RC522-RFID module from MIFARE (https://www.mifare.net/).

The RFID module needs to be powered by a 3.3V DC power source. It reads the tag ID numbers of the RFID tags near it, and passes them to the Photon to which it is connected. The tags are passive, and don't need any power supply...

Ajith Vasudevan

Ajith Vasudevan is an electronics, computer, and IoT enthusiast who likes to apply his knowledge in these fields to make modern living easy for himself and others around him. He has a bachelor's of technology degree in electrical and electronics engineering. He was interested in automation and IoT even before the term IoT became commonplace. He designed and built an automatic overhead-tank motor operator using $1 worth of electronic parts back in 1995, which is operating at his parents home to this day. He has automated and made it simple and efficient to operate many household appliances, for example, an automatic geyser switch that turns itself off after 10 minutes, saving electricity. It can be set to switch on at any specified time or can be controlled from anywhere. Today, even his friends and neighbors use this system. Ajith has worked in the heavy electrical industry before joining his current employer, Infosys Technologies Limited, in the year 2000. He is presently a senior computer scientist at EdgeVerve Systems, a subsidiary of Infosys. At work, he enjoys programming and has done so for over a decade and a half.
