The main advantage is the ability to connect the 3.3V NRF24L01+ module directly to 5V Arduino boards without complex voltage divider circuits or external power supplies.
If the measured humidity the threshold, the DO pin goes LOW .
While the adapter board is the most common result for "YL-105" in electronics hobbyist circles, it can also refer to a YL-105 Infrared Motion Sensor Alarm
: Determine whether you have a security alarm, voltage regulator, stove fan, pressure switch, or another device type. Look for markings on the product, such as labels, part numbers, or manufacturer names.
: For a "3/4" tubing, the supplied internal diameter (ID) is 0.75 inches. After full recovery (shrinking), the ID will reduce based on the ratio (e.g., to 0.375" for 2:1 or 0.25" for 3:1). yl-105 datasheet
to test the communication. Would you like to see a basic "Hello World" transmitter code?
| Module Code | Typical Function | |-------------|------------------| | YL-105 | Possibly (NTC thermistor + LM393) or laser receiver module ? (Unconfirmed) | | YL-69 | Soil moisture | | YL-83 | Rain/water drop | | YL-38 | Metal touch sensor |
The rugged design makes it suitable for extrusion machinery 1.2.3 .
Want me to expand this into a full short story or turn it into a sci-fi script? The main advantage is the ability to connect the 3
This is the most common configuration – active low. Check your specific module for an output LED indicator; when the LED lights up, the output is active (usually LOW).
The YL-105 is very popular in the Arduino community due to its simple interfacing. Wiring Diagram YL-105 Pin Arduino Pin GND DO Pin 2 (Digital) AO A0 (Analog) Example Code (Analog)
To read data from the YL-105, you do not need a specific library for the module itself, but rather a library for the being used (e.g., RC Switch, VirtualWire).
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: Look for markings on the product, such as
