The YL-105 internally uses a 555 timer or a parallel RC oscillator. This is noisy. Build a better driver using a NE555 in astable mode (100kHz, 50% duty cycle) to drive the probe. Read the voltage via a peak detector. This yields a 10x improvement in stability over the stock "better" datasheet.
The (often designated as YL105 ) is primarily known as a specialized power adapter board designed for the nRF24L01 wireless module. While the name can also appear in industrial metal contexts (like the L105 aluminum alloy), its most common "datasheet" usage refers to this essential electronics component.

The YL105 is a type of NPN (Negative-Positive-Negative) transistor, which is a commonly used semiconductor device in electronic circuits. It is designed for general-purpose applications, including amplification, switching, and voltage regulation. The YL105 transistor is known for its high current gain, low saturation voltage, and high reliability. Read the voltage via a peak detector
Stable power ensures the power amplifier (PA) in the nRF24L01 functions at maximum efficiency.
High-quality datasheets include efficiency vs. load graphs, typically peaking between Thermal Protection:
A truly better datasheet would be a living document, including application notes, oscilloscope captures, and a failure mode analysis. Until then, treat every YL-105 datasheet as a starting point, not an ending one. Probe the signals, test the limits, and always— always —design with a safety margin. In the world of relay modules, the difference between a prototype and a product is the quality of the questions you ask of the datasheet. Ask better questions, build safer circuits.
