Automatic soap dispensers (also known as soapy or non-touch soap dispensers) emit a number of controlled soap solutions (or similar liquids such as hand sanitizers). They are often used together with an automatic faucet in public toilets. They serve to save the amount of soap used and stem the transmission of infectious diseases.

Histori
The idea for the first dispenser was submitted by Guey-Chaun Shiau to be patented in 1989. The patent is under the name, "Automatic Dispenser Cleaning-Dispensing Device". This patent was issued in 1991. The patented device is under the following description: "An automatic discharge removal apparatus includes: a structure containing for cleaning fluid, a sensing means discharged on a base member mounted at the bottom of said containing structure wherein the base is provided with an outlet, a sensing circuit located on a circuit board, a motor arrangement connected electrically to the sensing circuit, an outlet for passing a light source from its sensing circuit to detect the presence of an external object close to the light source, and the discharge mechanism, comprising a thrust structure functionally connected to a driving motor and a pumping structure operatively engaged with a thrust structure, fixed to the base member associated with the sensing device, external objects close to the sensing device, the amount given from the cleaning fluid contained in the containing structure will be automatically provided for cleaning purposes. ".

Apps
The implementation of automated toilet fixtures has increased dramatically. Increasing numbers of public and private institutions have combined technology without touching their toilets.
Public locations
Automated technology has absorbed public toilets. Journalist Michael Sasso once called it, "The Hygienic Company Brings the Space Age to the Bathroom." He wrote a reference to Tampa International Airport. The first automated urinal was implemented in 1987 and in 16 years, "the airport has 143 automatic urinal, 390 automatic spinning linkec and 276 automatic faucet". Touchless technology has become a regular component of modern restroom facilities.
Hospital settings
A study was conducted in the area of ​​clinical microbiology laboratory accession and outpatient dental departments at the University of Virginia Medical Center. Studies were conducted to evaluate certain antiseptic solutions and automatic dispensers in hospitals. The study was conducted over two months, at the conclusion, the effectiveness of solutions and dispensers were surveyed. Although certain alcohol antiseptics are not favored because of the drying effect of the skin from alcoholic solutions, the dispenser itself is recommended for greater use throughout health care facilities.
The defilements, poverty, diseases that infiltrated the nineteenth-century society were drastically reduced by the revolutionary sanitation movement throughout the twentieth century. Despite some other advances... can be etiologically and temporally related to some of these diseases, the causal evidence (eg, temporal order, consistency, biological sense) is consistent with the hypothesis that personal hygiene is one of the other factors that helps to define decline. The progress of cleanliness, such as from automatic soap dispensers, can be regarded as one of the silent victories of public health and continues to be an important disease prevention strategy, even in this "modern" era when the "gospel gospels" have diminished in popularity.
A strong consequence of the reduction in mortality rate is hand washing (National Center for Health Statistics).
Mechanism
When washing hands, the user's hand is placed under the nozzle and before the sensor. The activated sensor will activate further the pump which dispenses a measurable amount of soap from the nozzle.
Radar-based sensors
This type of sensor sends microwaved bursts or ultrasound energy and waits for energy to reflect back. In a stagnant situation, energy will bounce back in the normal pattern. When the hand is placed in the basin, the energy emitted from the sensor will bounce back irregularly that triggers the soap dispensation. Modern sensors used in electronic taps, electronic sprinklers, and soap dispensers use infrared light with wavelengths in the range of 850 nm. Sensors use emitter and collector. The emitter emits infrared light pulses while the collector, positioned to face in the same direction as the emitter, "sits" inactive waiting to feel the pulses emitted. When no hands are present in front of the device, no reflection of light occurs, and therefore, no pulses are felt. When the hand is present in the transmitted light path, the part of the emitted infrared light bounces back toward the collector which is then rejected by the light (if photodiode is used) and produces a voltage to replace the pump. If the photo transistor is used, then the photo transistor, after sensing the infrared pulse, will only activate the pump.
Photo sensor
This mechanism consists of two parts, a focused light source (usually a laser beam) and a light sensor. When the user's hand is placed in the light beam line, the pump mechanism is activated by the disturbance felt by the light sensor.
Passive infrared sensor
The infrared sensor detects the infrared energy emitted by one's body heat. When the hand is placed near the sensor, the rapid infrared energy fluctuates. This fluctuation triggers the pump to activate and dispose of the amount of soap specified.
Benefits
Touchless
The progress of automatic soap dispensers is increasingly creating a more sterile environment. When various individuals use a pump, they will leave various bacterial colonies. These colonies will cross-breed and cause a more resistant bacterial strain that can recriminate different hands and will not be completely eliminated by the anti-bacterial soap. The wider spectrum or higher resistance level, in the present colony, is due to the interaction and/or complementation between resistance genes. Without having a diverse range of individuals touching the pump, the bacterial transmission will be eliminated.
Gradual preset
The dispenser will only distribute a certain amount of soap per movement activation. The specified amount to be shared can be set to a very efficient amount at which waste will be minimal.
Versatility
The dispenser mechanism that works for soap can also work for other liquids: soap, hand sanitizer, lotion, detergent etc. Various possibilities expand the use of dispensers to various locations other than the bathroom.
Racial bias
If the photo sensor-based dispenser is not designed correctly, it may only detect a narrow range of skin tones.
