A for the YL-105 does not exist as a single document from the module maker. The professional approach is to combine the LM393 comparator datasheet , the IR phototransistor datasheet (from a known equivalent), and a reverse-engineered schematic . This yields all necessary electrical, optical, and timing specifications for reliable integration into embedded systems.
Without this, the module becomes a fire hazard in continuous-duty applications.
With Analog data, you can program logic like: "If the rain value is < 500, close the skylight. If it's < 200, turn on the emergency sump pump." yl105 datasheet better
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.
Most YL-105 modules use generic 5mm IR components. Look for markings (e.g., "PT334-6C" or "5mm IR"). A comes from a known equivalent part: A for the YL-105 does not exist as
After reading this deep dive into the analysis, ask yourself:
When comparing the YL105 adapter to a direct connection, the advantages are clear: : Standard Arduino pins often provide only . The YL105 leverages the rail to provide up to Without this, the module becomes a fire hazard
Most online sources offering a YL-105 datasheet contain only:
: If you still experience poor range even with the YL105, ensure your antennas are not obstructed and that you are using a High PSRR Regulator setup if the environment is electrically noisy.
