hi team,

do you have any design guide or design tool for LEVEL Sensor, REFERENCE LIQUID Sensor, REFERENCE ENVIRONMENT Sensor?

we have no knowledge on how to select this sensor for liquid level sensing.

thanks.

Hi Kelly

It should have deign guide document, and hardware circuit reference with device product in the https://www.ti.com/tool/TIDA-00317, may I know more detail what you feel missing and need?

hi Terry,

thanks for your reply. I want to check how should we decide the Rigid-Flex PCB each layer size so that it can fit the sensor to customer use case

First, you maybe can calculate how much capacitive value customer need for their liquid level sensing case from below paper.

Then, you maybe can check the relationship between the captative value and the sensor layer/size/material from below paper .

Hello Kelly,

In addition to Terry's comments, you should also consider the size of the container that you are trying to sense and the resolution needed. These will have an impact on your sensor design and are a good place to start.

Best Regards,
