Yspring Internet of Things Solution：Application of water level monitoring in smart products without visual inspection
Water level data is closely related to human social life and production. The planning, design, construction, and management of water conservancy projects require water level data. Water level data is also required for the construction of bridges, ports, waterways, water supply and drainage projects. In flood prevention and drought relief, water level data is more important as it serves as the basis for hydrological forecasting and information. When the water level exceeds a specific height, there will be disasters such as waterlogging and dam breaches
Only by accurately and systematically sensing water level changes can we seek benefits and avoid harm in the process of responding to water level changes, and take effective measures to regulate water levels. In addition to the water level that occurs in the natural environment, smart products we use in our daily lives also have water level monitoring, such as common automatic hand sanitizers, drinking water heaters, atomizers, washing machines, hanging irons, etc. Water level monitoring can prevent machines from dry burning without water and motor idling
Real time monitoring, clean hands
Automatic hand sanitizer machines are usually installed in public places. As a high-tech hygiene product, compared to traditional manual soap dispensers, automatic hand sanitizers can effectively avoid cross infection during use. They are convenient, hygienic, environmentally friendly, low-carbon, and have a longer service life.
Compared to traditional hand pressed hand sanitizer containers, automatic hand sanitizer machines automatically control the dispensing process. Therefore, in the past, the outer shell was usually made of non transparent materials, making it more aesthetically pleasing.
However, because it usually uses a non transparent shell, it is impossible to see whether there is no liquid inside the container. If manual detection is used, it will inevitably be very troublesome. If it is installed in hospitals, stations, and other places, the detection of hand sanitizer in large areas and scattered throughout the area is very time-consuming. If a liquid level sensor is used for detection, it can detect in real time whether there is a shortage of liquid, and give a signal reminder when the liquid level reaches the set liquid line. If the automatic hand sanitizer machine is connected to the cloud backend at this time, the management personnel can check which area of the machine has a shortage of liquid through a computer or other means, and then increase the liquid or replace the container
Yspring Liquid Level Detection Device
The liquid level detection device is a product developed based on Yspring YS65F804. It uses the inductive capacitance of water in non-metallic containers to detect the presence of liquid. When there is no liquid approaching the sensor, the sensor has a certain static capacitance to the ground due to the distributed capacitance on the sensor. As the liquid level gradually rises and approaches the sensor, the capacitance of the copper foil to the ground continues to increase (the dielectric constant of water is 70 times that of air at room temperature). The changed capacitance signal is then input to the control IC for signal conversion, converting the changed capacitance into a certain electrical signal change. Then, a certain algorithm is used to detect and judge the degree of this change, thereby achieving real-time detection of the liquid level.
Main features:
1. The working voltage is between 2.4v and 3.6v
2. Low standby power consumption
3. Use with non-metallic containers (glass bottles, plastic bottles)
4. Less peripheral circuits
