Note:
1. detected when the liquid is water, the water level is lower than the critical level, water vapor, water vapor or water droplets in the sensor Surface of the body assembly, thereby leading to the signal output voltage decreases.
Therefore, in practical application, taking into account the water vapor, water vapor, water droplets or affect, the set value of the threshold voltage level VT, that is, if greater than the output voltage signal terminal VT, it is determined that the level is below the critical level, the output voltage signal terminal
If less than VT, the level is higher than the critical level is determined.
VT general value of 0.25-0.5V, specific values according to water vapor, water vapor or droplets generated and the impact of process degree determined. When the liquid to be detected for the other, it will also be affected by the droplet, it is also considered press law.
2 Consider the level of fluctuation characteristics, image stabilization to join in the program logic.
3 This section level sensor is not waterproof, the entire probe can not be placed in the liquid used.
4. Actual use, the level sensor probe surface can not have too much dirt, and if so, please immediately cleaned, Cleaning the surface of the detection process can not damage it.

Use and testing

 

The level sensor is installed above one way, and then connect the following circuit, the output signal terminal condition consistent with the level of the voltage signal, this signal is used as the liquid level control signal access MCU (micro controller) A / D (analog when digital converter) ports, when the level exceeds a critical level and flooded the sensor body, then the signal output is low voltage, when the liquid level is below the critical level and reveal the sensor body, then the signal output is high voltage.
