: The recovered wall thickness is vital for mechanical protection and insulation.

As moisture accumulates, the sensor's conductivity increases, causing the analog output voltage to decrease (or increase, depending on the module configuration).

Detects when soil is too dry (needing water) or sufficiently wet, allowing for the automation of irrigation systems. 2. Technical Specifications (YL-105 Datasheet) yl-105 datasheet

: Many YL-105 products include manufacturer identification like "YILIN", "BISUTIME", or other branding. The manufacturer's name is often the most critical piece of information for finding the correct datasheet.

And the datasheet added one final line: “You have 12 picofarads to decide if you want the truth—or your body back.”

| Specification | Details | | :--- | :--- | | | YL-105 | | Compatibility | nRF24L01, nRF24L01+ (including PA+LNA variants) | | Voltage Regulator | AMS1117 3.3V LDO | | Input Voltage (VCC) | 5V DC (derived from Arduino 5V pin or external supply) | | Output Voltage | 3.3V DC for the connected radio module | | Logic Level | Inputs from the host microcontroller are typically 5V tolerant. | | I/O Pins | 7 pins: GND, VCC, CE, CSN, SCK, MOSI, MISO | | Dimensions (LxWxH) | Approx. 26 x 18.6 x 10 mm |

The YL-105 adapter has a standard 7-pin male header for connection. The following connections are required for operation (based on standard Arduino Uno/Nano pin mapping): : Connect to 5V power (External or Microcontroller 5V pin)

The YL-105 operates as an intermediate power conditioner. While it alters the supply voltage to safe thresholds, it passes the SPI data lines directly through to the microchip breakout header.

5V DC (accepts 5V input from Arduino or other microcontrollers). Output Voltage: 1.9 ~ 3.6V DC (provides a regulated 3.3V).

The designation typically refers to two distinct types of devices in the electronics world: a PIR Motion Sensor Alarm unit and a Transceiver Adapter Module used for wireless communication.

The is a highly efficient voltage regulator and socket breakout board explicitly engineered to power and interface the popular nRF24L01+ 2.4GHz wireless transceiver module . While the nRF24L01+ requires a strict 1.9V to 3.6V power source, standard microcontrollers like the Arduino UNO deliver 5V logic and power. Attempting to power an nRF24L01+ module directly from an unregulated 5V rail can instantly fry the chip, while utilizing the Arduino's on-board 3.3V pin frequently causes connection drops due to inadequate current supply. The YL-105 socket board addresses this hardware bottleneck by incorporating an on-board AMS1117 3.3V step-down linear regulator and local decoupling capacitors to provide a clean, dedicated power stream.

: Determine whether you have a security alarm, voltage regulator, stove fan, pressure switch, or another device type. Look for markings on the product, such as labels, part numbers, or manufacturer names.

The YL-105 is versatile and used across several heavy industries, including oil refining, petrochemical engineering, sewage treatment, and pharmacy. It is most commonly found in: YALAN Seals Centrifugal pumps Screw pumps Paper-making equipment YALAN Seals Other Potential "YL-105" References Depending on your industry, you might also be looking for: UVAFLEX YL-7M105FCM: A very low-odour matt lacquer Zeller + Gmelin , specifically used for food packaging and labels (FCM) SE-K 105°C Capacitors: A range of aluminum electrolytic capacitors

The LM393 does not have built-in hysteresis, but many YL-105 modules add a small positive feedback resistor. Check your board; if not present, you may experience output jitter near the threshold. The datasheet often omits this, so add hysteresis in software (debouncing) or external resistors if needed.
