Yl-105 Datasheet
Proper placement is critical for optimal performance. Because PIR sensors achieve highest sensitivity when a person moves laterally (across) the lens rather than directly toward or away from it, the installation angle and height significantly affect the protection area. Manufacturers recommend mounting the universal base at approximately 2 meters (about 6.5 feet) above ground level. The unit should be positioned at a 10–30 degree angle from the wall for maximum detection distance, and the protected area must remain unobstructed for clear line-of-sight.
: Optional pin to mask or trigger hardware interrupts for data-ready or transmission-sent flags. ⚡ Circuit Diagram and Schematic Overview

The is a specialized power management and prototyping interface designed specifically for the popular Nordic Semiconductor nRF24L01+ 2.4GHz wireless transceiver modules . It bridges the gap between 5V microcontrollers like the Arduino UNO and the strict 3.3V power requirements of the radio transceiver. By incorporating an on-board AMS1117 3.3V linear voltage regulator and filtering capacitors, the YL-105 eliminates communication errors caused by voltage drops and protects delicate RF circuitry. 🛠️ Complete Technical Specifications
: SPI standard low-active select line for bus communication. Proper placement is critical for optimal performance
A voice—not audio, but felt—rippled through his mind: “Hello? Is anyone there?”
It breaks out the double-row pins of the nRF24L01 into a format that is easier to wire with standard jumper cables. The unit should be positioned at a 10–30
For the full technical documentation, you can access the Alpha Wire FIT-300 Spec Sheet or the general FIT Heat-Shrink Tubing Catalog on DigiKey.
This is a breakout board designed to solve the common power issues of nRF24L01 wireless modules. It includes a voltage regulator (AMS1117) that allows you to power the radio module using a 5V source instead of its native, sensitive 3.3V requirements. 4.8V to 12V DC. Output Voltage: Stable 3.3V (regulated for the nRF24L01).
