How to realize the technology of touchless design of automatic soap dispenser

In the field of hygiene, the automatic soap dispenser is undoubtedly a very innovative technological product. As one of its important features, the non-touch design provides users with a more hygienic and convenient hand-washing experience.
Applications of infrared sensing technology:
The key to touchless design lies in the application of infrared sensing technology. The smart hand sanitizer automatic sensor has built-in high-precision infrared sensors that can detect infrared radiation in the surrounding environment. When a user places their hand within the sensing range, the infrared sensor accurately captures the position and movement of the hand.
The key steps to achieve touchless design using infrared sensing technology are as follows:
Infrared radiation detection: Infrared sensors emit infrared beams that are reflected or absorbed by the hand. When the user's hand enters the sensing range, the infrared sensor receives the reflected beam or senses the weakening of the beam, triggering the sensor's operation.
Signal interpretation and processing: After the sensor receives the signals sent back by the infrared sensor, these signals need to be interpreted and processed. This process is usually taken care of by the internal microcontroller, which determines the position and movement of the user's hand based on a preset algorithm.
Trigger hand sanitizer release: Once the sensor determines the presence of the user's hands and recognizes the correct movement, it triggers the system to release the appropriate amount of hand sanitizer. This step ensures that users do not need to touch any equipment during hand washing, thereby reducing the risk of cross-contamination.
Engineering adjustment of sensing range and sensitivity:
In order to ensure the accuracy and stability of touchless designs, the sensing range and sensitivity need to be finely tuned in the engineering design. This requires comprehensive consideration of factors such as the user's hand size, movement speed, and surrounding lighting conditions.
Adjustment of the sensing range: In order to make the user experience more natural, the sensing range needs to be neither too narrow to cause false triggers, nor too wide to cause user needs to be accurately perceived. Through engineering adjustments, the sensing range is ensured to meet both hygienic requirements and user convenience.
Precise control of sensitivity: The adjustment of sensitivity directly affects the response speed and false trigger rate of the system. By precisely controlling the sensitivity of the infrared sensor, the system can ensure that the system senses the user's hand quickly and accurately, avoiding unnecessary trouble.
Power and energy-saving optimization of touchless design:
In order to make the smart hand sanitizer automatic sensor more intelligent and sustainable, the touchless design also needs to consider power management and energy-saving optimization.
Low power consumption design: Since the sensor needs to maintain monitoring status for a long time, low power consumption design is an important factor to ensure stable operation of the equipment. The use of low-power electronic components and optimized circuit structure can extend battery life and reduce the frequency of battery replacement.
Smart Sleep Mode: To further save energy, touchless designs often include a smart sleep mode. When the system does not detect hand activity for a long time, the device will automatically enter a sleep state to reduce energy consumption. Once hand activity is detected again, the system will wake up quickly to ensure that the device responds to user needs in a timely manner.
