The YL-105 is a low-cost, low-power wireless transceiver module designed for various short-range wireless applications. It is based on the RF chip by AMICCOM. It operates in the 2.4GHz ISM band (Industrial, Scientific, and Medical frequency band).
: Features a 2:1 shrink ratio with a relatively low shrink temperature of 90°C , allowing for fast installation without damaging heat-sensitive parts.
The YL105 datasheet provides detailed information about the component's electrical characteristics, thermal properties, and mechanical specifications. Here's a summary of the key points:
Optional, active-low notification pin from the radio to host MCU. 🔬 Circuit Architecture & Component Breakdown yl105 datasheet
These chips are sensitive to voltage spikes. Ensure the regulated DC voltage reaching the chip is stable.
Aris slammed the datasheet onto the table. “YL105. NPN Silicon Phototransistor. ” He read the lines aloud, as if they held a secret.
Wireless transmissions can cause sudden current spikes. The onboard voltage regulator and filtering capacitors provide a stable current, preventing random disconnections or module resets. Technical Specifications & Parameters The YL-105 is a low-cost, low-power wireless transceiver
Note: This contrasts with high-end industrial sensors that use the "nephelometric" method (scattering), where the sensor detects light scattered at 90 degrees. The YL-105’s transmission method is cheaper to manufacture but more susceptible to errors if the optical window becomes dirty.
The YL105 transistor has a wide range of applications due to its versatility and reliability. Some common applications include:
Dual output, easy to use, wide voltage range, open-collector digital out. The bad: No thermal specs, mediocre linearity, PCB lacks shielding, sparse documentation. : Features a 2:1 shrink ratio with a
Receives signals from buttons or sensors (e.g., a steam sensor in a kettle).
Connects directly to the 5V output pin of your microcontroller or single-board computer (SBC).
Data line. Connect to SPI MISO (e.g., Pin 12 on Arduino Uno).
