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 YL-105 designation spans multiple completely unrelated product categories, from security systems to voltage regulators, stove fans to industrial sensors. For engineers, hobbyists, and technicians, accurate identification of the specific YL-105 device in hand is the critical first step toward finding the appropriate technical documentation. The most common applications fall into two major categories: the PIR motion sensor alarm for security applications and the 5V-to-3.3V voltage regulator for Arduino and electronics projects. Always verify the product's physical characteristics, manufacturer markings, and intended application before assuming which documentation applies.
Aris ran a cross-reference. Only one known device used that phrase: the , reportedly tested in a black-site lab in 2043. The project was scrubbed after a “containment breach.” All six test subjects died. Official cause: cardiac arrhythmia. Unofficial rumor: their brain patterns got copied into the chips. yl-105 datasheet
The onboard LM393 comparator acts as a threshold detector. There is a small potentiometer (blue component) on the board. You can adjust this to set a specific humidity level.
This sensor is generally not suitable for extreme moisture condensation conditions or very precise laboratory applications. If you'd like, I can: Show you a schematic for the relay circuit. Provide code for calibrating the sensor . Search the web or a marketplace (Amazon, AliExpress,
The YL-105 adapter board features a built-in voltage regulator to convert 5V to the required 3.3V, providing stable power to the transceiver.
Provides an analog voltage proportional to the humidity level. 4. Working Principle Aris ran a cross-reference
A wireless infrared motion sensor alarm model YL-105 exists, typically used in garages or sheds.
