D6T thermal sensor and People Counting Algorithm In this thesis work, a new indoor people counting algorithm is created by using Omron D-6T thermal sensor and Raspberry Pi. The sensor periodically generate thermal map of heat emitted in its field of view which is a one dimension array and pass the array to Raspberry for further processing. The people counting algorithm is created in Raspberry Pi by processing thermal map generated by D6T. After processing the number of people indoor is obtained. This chapter presents the hardware structure used including D6T thermal sensor and Raspberry Pi, moreover the people counting algorithm is discussed in detail.

The master node generates the clock and initiates communication with slaves while the slave node receives clock signal and give a response to the master when its address is requested. It is necessary to stress that I2C bus is a multi-master bus which means any number of master nodes can be attached. Usually a bus device operates in one or two modes of four modes operation which are master transmit, master receive, slave transmit and slave receive. Initially the master starts master transmit mode by sending a start bit followed by the address of the slave it wished to communicate with, after this a command would be sent and tells the slave whether it would write or read from the slave. If the slave exists on the bus and it will shake hands with master by sending an ACK bit (active low for acknowledged). â€Å"S† Start Condition â€Å"Sr† Repeat Start Condition â€Å"P† Stop Condition â€Å"W/R† Write(Lo)/Read(Hi) â€Å"ACK† Acknowledge reply â€Å"NACK† No-acknowledge reply Figure 4.
