The following specifications are typical for a YL-105 adapter:
: Emits a piercing 105dB alarm to deter intruders.
, a common resistive sensor often used for environmental detection in DIY electronics and smart gardening projects. Understanding the YL-105 Sensor Module: Datasheet & Guide
If you have downloaded the YL-105 datasheet (or the 49E sensor datasheet which is 90% relevant), pay close attention to these sections: yl-105 datasheet
The YL-105 is not a bare Hall effect IC; it is a . It typically features a 49E (or equivalent) linear Hall sensor, a comparator circuit (often an LM393), a potentiometer for adjustable sensitivity, and onboard power regulation. The module outputs a clean digital signal (HIGH/LOW) based on the presence of a magnetic field, making it directly compatible with 3.3V and 5V microcontrollers like Arduino, Raspberry Pi, and ESP32.

Search the web or a marketplace (Amazon, AliExpress, eBay) for "YL-105 module" . Look at the listing title to see what it detects. Common YL modules include: The following specifications are typical for a YL-105
: Triggers only when heat signatures (like a person) move through its field of view. 2. YL-105 Mechanical Seal
The YL-105 alarm uses a dual-element infrared sensor combined with a dedicated integrated circuit, offering low false-alarm rates and excellent cost-effectiveness. When motion is detected within the coverage area, the unit emits a loud 105 dB alarm sound for approximately 30 seconds. If motion persists after a 5-second delay, the alarm will trigger again, repeating the cycle. The two included infrared remote controls allow convenient arming and disarming of the system.
The AO pin is rarely used in simple digital applications. It provides a voltage between 0V and VCC proportional to the magnetic field strength, useful for linear position sensing or magnetic field strength measurement. It typically features a 49E (or equivalent) linear
Detects when soil is too dry (needing water) or sufficiently wet, allowing for the automation of irrigation systems. 2. Technical Specifications (YL-105 Datasheet)
The nRF24L01+ module is notoriously sensitive to power issues. When using 5V systems, connecting the module directly to 5V will burn it out. Using the 3.3V pin on an Arduino frequently provides unstable power, leading to erratic wireless communication. The board provides: Safe Voltage: Proper 3.3V regulated power supply.
In industrial contexts, the YL-105 is a standard mechanical seal used for pumps.
