// Thermal PCB Inspection
HotSpotter turns your USB thermal camera into a professional PCB inspection tool. Calibrated temperature readings, real-time thermal imaging, and multi-camera support — all in a clean Windows desktop app.
typically refers to a specific mechanical seal model used in industrial pumping applications. While "YL-105" can occasionally appear in other catalogs (like UV lacquers or capacitors), the primary datasheet information describes it as a reliable component for chemical and sewage pumps.

Since no official datasheet exists for "YL-105" as a unique component, your best document is the datasheet for the main IC + a generic schematic for that module type. yl-105 datasheet
If you are interested in learning more about the YL-105 or would like to obtain a copy of the datasheet, you can visit the following resources:
Common calibration: Place the sensor 5mm above a white surface. Turn the potentiometer until the onboard LED just turns off. Now, the module will trigger reliably when seeing white vs. black. typically refers to a specific mechanical seal model
Below is an informative paper summarizing the specifications, pinout, and application of the YL-105 module. 🛰️ Device Overview
Expansion/Recovery: For a "3/4" tubing, the supplied internal diameter (ID) is 0.75 inches. After full recovery (shrinking), the ID will reduce based on the ratio (e.g., to 0.375" for 2:1 or 0.25" for 3:1). Share your calibration tips or code snippets in
Wall Thickness: The recovered wall thickness is vital for mechanical protection and insulation.
