We are developing a low cost people counter based on arduino and ultrasonic range finder sensors.
Hardware:
- Arduino Pro Mini 16 Mhz
- UHC-SR04 ltrasonic range finder
- DHT11 temperature and humididty sensor
- Real time clock module
- Micro SD card slot
- I2C LCD display
- 4 x 4 Matrix Keypad
- Lithium Ion battery
Features:
- Detect and record count, date, time, direction of travel, and speed for each detected object
- Record the data in CSV format on micro SD card
- Multiple profiles for different use cases
- On-device configuration
