Yl-105 Datasheet Info

If you find a seller listing YL-105 as a "laser sensor" or "photoresistor module," that is your clue.

| Condition | Digital Output (DO) | |-----------|---------------------| | No magnetic field (or very weak) | Logic HIGH (VCC) | | Strong magnetic field (south pole) | Logic LOW (0V) | yl-105 datasheet

If the measured humidity the threshold, the DO pin goes LOW . If you find a seller listing YL-105 as

Easier to wire than the standard 2x4 female headers found on the bare nRF24L01 module. Multi-Device Networking: Supports up to 6 data pipes (star network topology). Instructables 💡 Application Guidelines Software Libraries: RF24 Library for Arduino or the nRF24L01 Product Specification for custom SPI drivers. Power Note: Multi-Device Networking: Supports up to 6 data pipes

Typical wiring connections for Arduino projects using the YL-105 regulator:
