光学式管道液体传感器LL10AH 洗地机 缺夜保护

应用邻域 / Application

1. 洗地机/ Washing machine：

检测洗地机清水箱是否有水，给予用户提示加水。检测污水箱是否装满，给予用户提示需要倒出污水

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. 饮品设备/ Beverage equipment：

在出液设备前添加传感器，若管道内检测不到液体，代表此时设备饮料已经使用完了，给用户提示添加材料

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. 咖啡机/ Coffee machine：

在咖啡机的出水管进行安装，当水箱的水使用完后进行提示

Install the water outlet pipe of the coffee machine and provide a prompt when the water in the tank is used up

4. 自动添料设备（液体）/ Automatic feeding equipment (liquid)：

当材料使用完后需要进行提示或者保护

需要进行水泵空抽保护，缺液保护的设备都可以使用

原理及优势/ Principle and Advantages

1. 光学式管道液体传感器的原理/ Principle of Optical Pipeline Liquid Sensor

传感器利用光电效应和光的棱镜的折射效应进行检测管道内是否有液体的存在当管道内没有液体，传感器的红外发光源发出的光照射到棱镜上，会进行反射光电二极管接受到红外光，当管内有液体时，不会发生反射现象。受光器件便不会发生阻值的变化，由电阻的改变从而引发电压的改变，所以在MCU上检测电压的状态便可以得出管内有没有水

Sensors use the photoelectric effect and the refractive effect of prismsto detect the presence of liquid in pipelines When there is no liquid in the pipeline, the infrared light source of the sensor emitslight that reflects off the prism The photodiode receives infrared light and does not reflect when there isliquid 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

2. 优势，此传感器体积较小，安装快捷，方便，在检测过程中没有一点机械运动过程，使用寿命长。客户在使用此传感器开发方便，只需一个ADC接口便可。

Advantages: This sensor has a small size, is easy to install, and has no mechanical movement during the detection process The process has a long service life. Customers can easily develop using this sensor with just one ADC interface
