Generally speaking, the sensor based contactless faucet is composed of infrared transmitting circuit, infrared receiving amplifier circuit, control circuit, solenoid valve and power supply.
Proper hygiene is the key to preventing any disease, especially in the current covid-19 pandemic. Therefore, hand washing, disinfection and keeping away from frequently contacted surfaces are important components of the new normal. However, even if we wash our hands, we are bound to come into contact with some of the most common surfaces, whether at home or in public places – taps and fixtures. So it’s no surprise that the bathroom is a place where people are more likely to get infected.
It is reported that Casa Milano provides a simple and practical solution – sensor based contactless faucet. Azhar sajan, director of Milan house, said: “with our touch free faucets and fixtures line, we no longer need contact surfaces for good hand hygiene practices. Just put your hand in front of the sensor in the faucet and the water will flow out. Similarly, placing your hand in front of the sensor of the touch dispenser will automatically release the disinfectant without touching the surface. “
These taps and fixtures improve hygiene because they use technology to detect hand movement, and they use batteries or AC power, depending on the model chosen.
Generally speaking, the sensor based contactless faucet is composed of infrared transmitting circuit, infrared receiving amplifier circuit, control circuit, solenoid valve and power supply. At present, there are two kinds of power supply devices in the market, AC and DC.
So what is the principle of sensor based contactless faucet?
The first is the principle of electromagnetic induction. It regards people as conductors. When they are in the magnetic field formed by 50 Hz alternating current, electromagnetic induction will occur. As a result, the human body generates induced current, which reacts on the original electromagnetic field and changes the original current. When this change is received by the circuit, the water will be discharged through the electromagnetic relay.
And then infrared reception. The human body temperature is 37 degrees. When it is higher than the room temperature, it will radiate infrared rays. The sensor that receives the radiation will make the faucet run water.
Finally, infrared reflection. The infrared transmitting tube emits a bunch of infrared rays in the direction of water flow. When the hand reaches the faucet, the infrared rays are reflected by the hand, and the infrared receiving tube receives the infrared light, and sends the signal to the internal circuit. After the internal circuit processing, the power supply of the electromagnetic faucet is connected, and the faucet is turned on; when the hand leaves the faucet, the infrared rays are no longer reflected, and the power supply of the electromagnetic faucet is turned off, and the faucet is stopped Stop the water supply.
Sensor based taps and fixtures can be easily installed in kitchens, while water dispensers can be installed in different locations – bedrooms, living rooms, guest rooms, children’s rooms, elderly parents’ homes, outside bathrooms, even offices, restaurants, retail stores and any other public areas.
“The goal is to raise hygiene awareness and not touch anything when you want to wash your hands,” said sajan. These practical solutions are complementary to the current preventive measures during the pandemic. Avoiding exposure to viruses is a challenge, so using contactless taps and fixtures will be an important step in minimizing pollution. “
So, in addition to helping to protect families, installing sensor based taps and fixtures in workplaces and stores can also benefit businesses by increasing customer trust and confidence.
