Usage notes

If you want the exact PDF datasheet, tell me whether your YL‑105 has any markings (chip ID, manufacturer, or photos) or confirm you want a web search; I can fetch the official datasheet PDF.

Note: Since "YL-105" is a common PCB module designation (often sold on breakout boards with an LM393 comparator), this review assumes you are referring to the KY-024 / YL-105 linear Hall effect sensor module (based on the 49E or similar linear Hall element). If you meant a specific IC datasheet, this review covers the typical engineering specifications of the module itself. Overview: The YL105 is a low-dropout linear voltage

D. Open-Collector Digital Output

The LM393 output is open collector. The datasheet usually notes this, meaning you can pull it up to a different voltage (e.g., 3.3V for a Raspberry Pi) than the module’s VCC (5V). This is a major plus for mixed-voltage systems.

2. YL105 Pinout and Connections

According to the typical yl105 datasheet for the module version, you will find three or four pins:

| 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) |

For the bare Hall sensor IC (commonly a unipolar Hall switch like AH3144E): Low Dropout Voltage: The YL105 has a low

Wiring example with Arduino:

A 10kΩ pull-up resistor is often required on the output line if not already present on the module.

5. Opto-Isolation and Safety

One of the main reasons engineers search for the yl105 datasheet is to understand the isolation voltage. The YL105 uses a PC817 optocoupler, providing electrical separation between the low-voltage control side (microcontroller) and the high-voltage load side.

However, note that many low-cost YL105 modules do not maintain true isolation if the jumper JD-VCC is shorted to VCC. For proper isolation:

6. Differences from NRF24L01

While the YL-105 looks physically similar to the popular NRF24L01+ modules and uses the same SPI interface, they are NOT compatible.
