Request for PCB Reference Schematics: SEN0193 Moisture Sensor and SEN0508 Liquid Level Sensor
Fahed.Altermathy 2026-01-18 03:35:22 224 Views1 Replies Hello,
I am working on a senior design project and would like to better understand the electrical characteristics and recommended integration methods for the following sensors:
• Moisture Sensor (SKU: SEN0193)
• Capacitive Flexible Liquid Level Sensor (SKU: SEN0508)
If available, could you please share the PCB schematic diagrams or reference documentation for these devices? This information would be used strictly for educational purposes to ensure proper integration into our design.
Thank you for your time and support.
I think the PCB layouts are not open source. That's why dfrobot has not disclosed them. However, you can get the schematic of Moisture Sensor (SKU: SEN0193)
from here:

You can get the dimension diagram of liquid level sensor here.

If you want to design a minimalistic moisture sensor by yourself, you can follow this design.
