光學式管道液體傳感器

應用鄰域 / Application
1. 洗地機/ Washing machine ：
檢測洗地機清水箱是否有水，給予用戶提示加水。檢測污水箱是否裝滿，給予用戶提
示需要倒出污水
Check if there is water in the cleaning tank of the floor scrubber and provide
users with a prompt to add water. Check if the sewage tank is full and provide
users with a prompt to pour out the sewage
2. 飲品設備/ Beverage equipment ：
在出液設備前添加傳感器，若管道內檢測不到液體，代表此時設備飲料已經使用完
了，給用戶提示添加材料
Add a sensor before the liquid dispensing device. If no liquid is detected in
the pipeline, it means that the device's beverage has been used up and prompts
the user to add materials
3. 咖啡機/ Coffee machine ：
在咖啡機的出水管進行安裝，當水箱的水使用完后進行提示
Install the water outlet pipe of the coffee machine and provide a prompt when
the water in the tank is used up
4. 自動添料設備（液體）/ Automatic feeding equipment (liquid) ：
當材料使用完后需要進行提示或者保護
Prompt or protection is required after the material is used up
需要進行水泵空抽保護，缺液保護的設備都可以使用
Equipment that requires pump vacuum protection and liquid shortage

protection can be used
……
? 原理及優勢/ Principle and Advantages
1. 光學式管道液體傳感器的原理/ Principle of Optical Pipeline Liquid Sensor
傳感器利用光電效應和光的棱鏡的折射效應進行檢測管道內是否有液體的存在
當管道內沒有液體，傳感器的紅外發光源發出的光照射到棱鏡上，會進行反射
光電二極管接受到紅外光，當管內有液體時，不會發生反射現象。受光器件便
不會發生阻值的變化，由電阻的改變從而引發電壓的改變，所以在MCU上檢測
電壓的狀態便可以得出管內有沒有水
Sensors use the photoelectric effect and the refractive effect of prisms to detect the
presence of liquid in pipelines When there is no liquid in the pipeline, the infrared
light source of the sensor emits light that reflects off the prism The photodiode
receives infrared light and does not reflect when there is liquid inside the tube. The
light receiving device will not undergo a change in resistance, and the change in
resistance will cause a change in voltage. Therefore, detecting the voltage status on
the MCU can determine whether there is water inside the tube
