| Pin Name | Function | |----------|----------| | VCC | Power supply (3.3V – 5V DC) | | GND | Ground (0V) | | DO | Digital output (HIGH when magnetic field detected, LOW when absent – or vice versa depending on comparator configuration) | | AO | Analog output (rare on basic YL105; some variants omit this) |
The utility of the YL-105 breakout board spans across rapid prototyping environments and industrial use cases:
Connect the module as follows:
In the world of low-cost electronics and consumer appliances, specific integrated circuits (ICs) often become industry standards for their efficiency and simplicity. The is one such component. Often found in household devices like electric kettles, fans, and basic timers, understanding the YL105 datasheet is essential for repair technicians and hobbyist engineers alike. yl105 datasheet
Since an official unified datasheet for "YL105" is rare (the number often refers to a module, not a single IC), below are the derived from common Hall sensors used in YL105 modules.

Common Troubleshooting Tips
Unlike industrial Hall sensors (e.g., from Allegro or Melexis), the YL-105 datasheet provides . In practice, the analog output will drift significantly with temperature (±10% or more across 0-50°C). For indoor hobby projects, fine. For outdoor or industrial use? Avoid. Since an official unified datasheet for "YL105" is
By understanding the YL105 datasheet, designers and engineers can design and develop applications that utilize the device's features and capabilities. The YL105 datasheet is a valuable resource that provides detailed information about the device's specifications, features, and applications.
The analog response is smooth and repeatable (±2% variance between cycles). The digital trigger has about 2-3 mm of hysteresis due to the LM393's internal positive feedback (which is good—it prevents chattering).
Operating RF microcontrollers requires clean, noise-free voltage translation. The YL-105 relies heavily on an to safely drop microcontroller system voltages down to the 3.3V logic level required by RF silicon.
