Input Output Description
Ultrasonic Sensor -
HC-SR04
Sensor used to detect people in
crowd and send analogue signal
to microcontroller
Sends analogue
signals to
microcontroller
This is the HC-SR04 ultrasonic
ranging sensor. This economical
sensor provides to maximum
400cm of non-contact
measurement functionality with
a ranging accuracy that can
reach up to 3mm
IP rating: IP44 / indoor use

Memory It takes input from Arduino Store data for
future use
Used to store data
Acceptance Test:
1. Detect peoples:
Integrated people counting algorithm
Count the peoples get on/off total number and compartment changing number constantly.
2. Store data in Memory
Support SD card storage function
Communication protocols
3. Storage of Data:
Data is retained after resetting the device.
4. System storage:
Compact program size with the maximum limit of 4M.
Maximum space utilization of 6M of ROM.
5. Interrupt Functionality:
Correct detection and action on interrupts.
Resetting of the count on reset interrupt.
Start/Stop of Counting on Pause push button.
6. Wired Data Transmission:
Correct data displaying on the LCD.
Correct signaling on Testing LEDs.
Explanations:
- All supplies ready (IR sensor, bread board, resistors, Arduino, wires, computer)
- Connecting the IR sensor with the Arduino using wires and resistors
- Coding the IR sensor (I’m learning how to code using C language)
- Testing
-cross my fingers front of the IR sensor from point A to point B, make sure the sensor count enter
-cross my fingers front of the IR sensor from point B to point A, make sure the sensor count exit
-Transfer data to my partner
