Yl105 Datasheet Better !!exclusive!! -
The nRF24L01 datasheet specifies a strict operating voltage of . Most beginners try to power the module directly from an Arduino’s 3.3V pin. However, the radio module requires clean, "stiff" current during high-power transmission bursts, which many onboard microcontroller regulators cannot provide. This results in "voltage brownouts" that cause the radio to crash or lose packets. How the YL-105 Improves Performance

This mechanical configuration eliminates messy point-to-point wiring connections, lowering the risk of parasitic resistance or intermittent contact failure.

Because the YL-105 communicates via Serial, the code is surprisingly simple. We will use the SoftwareSerial library so we can keep the hardware USB serial port free for debugging messages on the Serial Monitor.

The YL-105 is a popular, low-cost capacitive soil moisture sensor. Unlike its resistive counterpart (the YL-69 or FC-28), the YL-105 uses a copper-plated probe to measure dielectric constant. In theory, this prevents corrosion. In practice, without a better datasheet , you face calibration hell.

Always check your actual device carefully. The nRF24L01 adapter is a small PCB (approx. 26×18 mm) with a voltage regulator and two rows of male pins. The PIR alarm is a plastic box (approx. 80×122×50 mm) with a Fresnel lens on the front and a battery compartment. Physical inspection is the surest way to identify which YL‑105 you have.
