Yl105 Datasheet !!better!! | PRO — 2026 |
1. General Description
The YL-105 is a low-cost, low-power wireless transceiver module designed for various short-range wireless applications. It is based on the A7105 RF chip by AMICCOM. It operates in the 2.4GHz ISM band (Industrial, Scientific, and Medical frequency band).
It is widely used in consumer electronics, wireless mice/keyboards, remote controls, and toy applications due to its high integration level and minimal external component requirements. yl105 datasheet
C. Hydroponics
In hydroponic systems, sudden spikes in turbidity can indicate root rot or nutrient precipitation. The sensor acts as an early warning system before the plants show physical symptoms. Important: The YL105 is NOT suitable for PWM
4. Timing Characteristics (Switching Speed)
For applications requiring high-speed switching (e.g., dimming, pulse control), the relay’s mechanical nature limits operation. Refer to these timing specs: Home automation (controlling lights
| Parameter | Typical Value | |---------------|-------------------| | Operate Time (energize to contact closure) | 10 ms | | Release Time (de-energize to contact open) | 5 ms | | Maximum Switching Frequency | 10 Hz (0.1 sec on/off) | | Mechanical Life | 10 million operations | | Electrical Life (rated load) | 100,000 operations |
Important: The YL105 is NOT suitable for PWM (Pulse Width Modulation) or rapid switching. Use a solid-state relay (SSR) for high-frequency control.
