With a 5V DC input, the DIY Automatic Hand Sanitizer Dispenser Kit with IR Sensor & Relay automates liquid output using a 3-6V submersible pump. Infrared detection triggers the relay within a 2-30 cm range. Under heavy road dust in BD, this touchless mechanism maintains sanitation without physical surface contact.
Key Features
- Touchless IR Detection: 2-30 cm infrared sensing range. Dispensing starts without physical contact to stop bacterial transfer.
- Adjustable Sensitivity: Integrated potentiometer for sensor calibration. Rotating the dial prevents false triggers from ambient light.
- Project Hardware Bundle: LM358/LM393 IC, relay, and 30cm pipe included. Components fit together for rapid prototyping of touchless systems.
- DC Submersible Pump: 80-120 L/h flow rate at 3-6V. Liquid reaches the nozzle via 1.1m maximum lift capability.
Frequently Asked Questions
What is the range of IR sensor in sanitizer kit?
The IR sensor detects objects between 2 cm and 30 cm. Use the onboard potentiometer to narrow or widen this detection zone.
How to connect IR sensor to relay for sanitizer?
Wire the sensor's digital output to the relay module's trigger pin. The relay then closes the circuit to power the 3-6V DC pump.
