Because the official documentation is sparse, you must create your own through calibration. Do not trust the voltage readings out of the box.
The breakout pins on the YL-105 align directly with the standard nRF24L01 pin assignment schema:
| Variant | Typical source | How to find the datasheet | |---------|----------------|---------------------------| | nRF24L01 adapter | Electronics components sellers (e.g., Tech Sul, Proesi, Electrochip) | Use the product description; the vendor often lists specifications. For schematic details, measure the board and trace the circuit—no official document exists. | | PIR motion alarm | Security equipment distributors, wholesale platforms (Made‑in‑China, Yiwugo) | Look for user manuals under the brands . Many include a multi‑page installation and operation guide. | | Pressure switch | HVAC suppliers, Yi Lin distributors | Download the YL‑1132A pressure switch manual; it contains data for the YL‑105 series. | | Network meter | Industrial automation suppliers (Hi1718, etc.) | Contact the seller directly for the technical datasheet, as it is rarely published online. | yl105 datasheet better
An internal temperature sensor triggers a safe shutdown if the junction temperature crosses safe limits. The datasheet specifies precise hysteresis values. These values ensure the component does not rapidly cycle on and off while cooling down. Under-Voltage Lockout (UVLO)
The nRF24L01 and nRF24L01+PA+LNA modules require a . Many Arduino boards (like the Uno or Nano) have a 3.3 V output, but that output often cannot supply enough current for reliable operation, especially when the radio transmits at high power. Moreover, the nRF24L01’s 2×4 pin header is physically awkward to breadboard. The YL‑105 adapter fixes both issues. Because the official documentation is sparse, you must
The YL-105 allows you to plug the radio module into the 8-pin female header, while the male pins interface directly with your Arduino. This eliminates wiring errors, as the 5V power, ground, and SPI communication pins are correctly routed. 3. YL-105 Schematic and Pinout
Understanding the precise electrical layout, voltage tolerances, and pin distributions detailed in an official datasheet protects sensitive RF silicon, eliminates intermittent packet drops, and speeds up product development. 📊 The Core Technical Specifications For schematic details, measure the board and trace
The SRWQ100-YL105-9001 residual chlorine sensor is a specialized, durable probe designed to measure the amount of active chlorine (HOCl) remaining in water after disinfection. It is widely used to ensure drinking water safety, manage cooling tower efficiency, and treat wastewater.
– it’s cheap, easy to use, and gives both analog and digital outputs. No, for professional use – lacks calibration, corrosion protection, and official documentation.
