Electronic hands-free/non-contact faucets and soap dispensers rely on sensors and electronic controls to provide touchless operation. Here's a general description of their operation:
Presence detection: When a user's hand or an object is detected within the sensing range of the device, the sensor activates.
Signal transmission: The sensor sends a signal to the electronic control unit, which processes the input.
Water flow or soap dispensing activation: Based on the input from the sensor, the electronic control unit triggers the appropriate action. In faucets, it may activate a solenoid valve to allow water flow, and in soap dispensers, it may engage a motorized mechanism to dispense soap.
Flow control: The electronic control unit regulates the flow of water or soap based on preset settings, such as duration or volume.
Deactivation: Once the sensor no longer detects the presence of a hand or object, the electronic control unit stops the water flow or soap dispensing action.
Electronic hands-free/non-contact faucets and soap dispensers offer convenience and hygiene benefits by eliminating the need for physical contact, reducing the spread of germs, and providing precise control over water or soap usage.
