An automatic hand sanitizer dispenser, integrated with an oximeter, a heart rate monitor, a non-contact body temperature sensor, and voice assistant feedback.
The project is developed and deployed on an Arduino UNO with the following sensors and devices
- Arduino UNO
- 9V Pump
- 9V Battery
- MAX30102 (Heart Rate Monitor & Pulse Oximeter)
Note: We include the MAX30105 header due to compatibility issues.
- Arduino MicroSD Card Module
- 8GB MicroSD Card
- PAM8403 Type-D Amplifier
- Speakers (around 3W / 4 ohm)
- 128x32 OLED
- MLX90614 (Infrared Non-Contact Thermometer)
- 5V Relay
- Ultrasonic Distance Sensor
- Breadboard and Jumper Wires
- Flash the code to the Arduino UNO via an appropriate COM port.
- Format the MicroSD card to FAT32 using an appropriate card reader. Then, extract and copy the files to it.
Note: Due to memory constraints, the code was split between two Arduino UNOs. An Arduino MEGA, having higher memory capacity, might be a more suitable option.
The Arduino IDE needs the following packages installed either manually or through the GUI package manager
