The YL-105 is often confused with or used in combination with popular sensors like the HR202 humidity sensor element. The module typically includes a humidity-sensitive resistive element and a comparator IC (such as LM393) to provide a clean digital signal alongside analog voltage changes.
The YL-105 datasheet is a comprehensive document that provides detailed information about the component's specifications, features, and applications. The datasheet typically includes the following information:
Provides a more stable current supply than many microcontroller 3.3V pins, which is essential because nRF24L01 modules are prone to data errors if power is unstable. Dimensions: Approximately 26 x 19 x 12mm Pinout Compatibility: yl-105 datasheet
The YL-105 datasheet provides detailed specifications that help designers and engineers understand its performance and limitations. Some of the key specifications include:
Because the probes use exposed metal, electrolysis occurs, causing the sensors to corrode quickly if powered 24/7. The YL-105 is often confused with or used

. While the nRF24L01 chip itself requires a 3.3V power supply, the YL-105 includes an onboard voltage regulator, allowing it to interface directly with 5V systems like an Arduino Uno. Instructables
: Raw DC power (5V–12V) feeds into the VIN node of the AMS1117-3.3 linear regulator. This steps the input down to a smooth, constant 3.3V DC rail. : SPI clock line provided by the master MCU
