Yl-105 Datasheet

Note: Some budget clones swap the pin order. Always check the back of your PCB for labels.

As moisture accumulates, the sensor's conductivity increases, causing the analog output voltage to decrease (or increase, depending on the module configuration). yl-105 datasheet

Digital TTL signal (0 or 1). Usually, it outputs Low (0V) when an obstacle is detected and High (VCC) when the path is clear. Note: Some budget clones swap the pin order

: Communities such as Arduino Forum, Electronics Stack Exchange, and Reddit's r/AskElectronics contain discussions from users who have worked with specific YL-105 devices and can provide practical guidance. Digital TTL signal (0 or 1)

I searched for a specific "YL-105" datasheet, but it is (like for a major IC, transistor, or sensor). This code is most likely used in one of two contexts:

The most common YL-105 product among electronics enthusiasts is a small breakout board that simplifies connecting the 2.4GHz NRF24L01 transceiver module to microcontrollers like Arduino, ESP32, and Raspberry Pi.
