Yl105 Datasheet Better _verified_ <Top 20 PRO>
is the standard for these modules and is highly recommended for stability. Troubleshooting
The headline "10A 250VAC / 10A 30VDC" is plastered on every datasheet. But better usage requires understanding the derating curve—which is almost never provided. For an inductive load (motor, solenoid, transformer), the inrush current can be 5-10x the steady-state current.

Standard development board regulators share their 3.3V pipelines with the main microcontroller unit (MCU) and any connected sensors. When the Go to product viewer dialog for this item.
The datasheet says "non-condensing environment." But if condensation occurs, the sensor requires 2 hours of drying at 50°C. Mount the YL105 vertically, not horizontally, so water drips off the PCB.
| Parameter | Value | |-----------|-------| | Operating voltage | 3.3V – 5V DC | | Current consumption | <20mA | | Comparator IC | LM393 (open collector output) | | Sensing area | Copper traces (corrosion-prone) | | Adjustable threshold | Via 10kΩ potentiometer | is the standard for these modules and is

The YL-105 datasheet ignores cable capacitance. If your cable to the sensor exceeds 30cm, readings drop by 10%.
The standard module includes a comparator (LM393) for digital output. Throw that away. The potentiometer drifts with temperature. For an inductive load (motor, solenoid, transformer), the
Most online sources offering a YL-105 datasheet contain only:
