Finding a datasheet for the specific part can be difficult as it is often a generic or localized part number used in specific regions or by smaller manufacturers.
SPI line transmitting data from the radio back to the MCU.
Could you describe the (number of pins) or the device this part came from to narrow down the exact datasheet? AI responses may include mistakes. Learn more S-821AA Series BATTERY PROTECTION IC FOR 1-CELL PACK
The YL105 datasheet reveals a 100nF decoupling capacitor on the power rails. The standard DHT11 module (the blue 3-pin version) often lacks sufficient capacitance. This means: yl105 datasheet better
For critical applications, avoid generic YL-105 modules and instead use a sensor with a full manufacturer datasheet (e.g., Sharp GP2Y0A21 or Vishay TCRT5000 reflective sensor).
The YL-105 addresses this exact problem by acting as an inline power stabilizer.

The datasheet mentions "VDD ripple < 50mV." In reality, if you power the YL105 from the same 5V rail as a servo motor, you will get +10% RH errors. Use a dedicated 3.3V LDO regulator or add a 470µF capacitor on the power rail.

This article serves as the for the YL-105. We will provide the missing specs, compare it against superior sensors, and show you how to extract professional-grade data from this cheap device.
Understanding the hardware configuration on the YL-105 helps explain why it provides better performance than a bare wire setup. 1. The AMS1117-3.3 Linear Regulator
