光學(xué)式管道液體傳感器

應(yīng)用鄰域 / Application
1. 洗地機(jī)/ Washing machine ：
檢測(cè)洗地機(jī)清水箱是否有水，給予用戶提示加水。檢測(cè)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(shè)備/ Beverage equipment ：
在出液設(shè)備前添加傳感器，若管道內(nèi)檢測(cè)不到液體，代表此時(shí)設(shè)備飲料已經(jīng)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(jī)/ Coffee machine ：
在咖啡機(jī)的出水管進(jìn)行安裝，當(dāng)水箱的水使用完后進(jìn)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(dòng)添料設(shè)備（液體）/ Automatic feeding equipment (liquid) ：
當(dāng)材料使用完后需要進(jìn)行提示或者保護(hù)
Prompt or protection is required after the material is used up
需要進(jìn)行水泵空抽保護(hù)，缺液保護(hù)的設(shè)備都可以使用
Equipment that requires pump vacuum protection and liquid shortage

protection can be used

? 原理及優(yōu)勢(shì)/ Principle and Advantages
1. 光學(xué)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(yīng)和光的棱鏡的折射效應(yīng)進(jìn)行檢測(cè)管道內(nèi)是否有液體的存在
當(dāng)管道內(nèi)沒有液體，傳感器的紅外發(fā)光源發(fā)出的光照射到棱鏡上，會(huì)進(jìn)行反射
光電二極管接受到紅外光，當(dāng)管內(nèi)有液體時(shí)，不會(huì)發(fā)生反射現(xiàn)象。受光器件便
不會(huì)發(fā)生阻值的變化，由電阻的改變從而引發(fā)電壓的改變，所以在MCU上檢測(cè)
電壓的狀態(tài)便可以得出管內(nèi)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
