Yl105 Datasheet Better Online

| Parameter | Value | Why it matters | | :--- | :--- | :--- | | | 3.3V to 5.5V | Better compatibility (works with 3.3V ESP32 & 5V Arduino) | | Humidity Range | 20% to 90% RH | Standard room conditions | | Humidity Accuracy | ±5% RH | Comparable to DHT11 | | Temperature Range | 0°C to 50°C | Indoor/Greenhouse focused | | Temperature Accuracy | ±2°C | Adequate for HVAC monitoring | | Sampling Rate | 1 Hz (1 reading per second) | Better stability than cheap clones | | Signal Type | Single-bus digital | Uses only 1 GPIO pin |

Hopefully this guide has helped you decode the mystery of "YL-105." By identifying the specific device you're looking for—whether it's an Arduino adapter, heat shrink tubing, or a security alarm—you can now find the right information and get back to your project. yl105 datasheet better

The DHT22 is more accurate (±2% RH, ±0.5°C) and has a wider range. So why would anyone say the YL105 is better? | Parameter | Value | Why it matters

This sketch reads a potentiometer (or just sends a static message) and transmits it to the receiver. This sketch reads a potentiometer (or just sends

: The RF transceiver operates exclusively between 1.9V and 3.6V DC . Connecting it directly to a 5V power rail will destroy the main IC instantly.

| Parameter | Value | |-----------|-------| | Operating voltage | 3.3V – 5V DC | | Current consumption | <20mA | | Comparator IC | LM393 (open collector output) | | Sensing area | Copper traces (corrosion-prone) | | Adjustable threshold | Via 10kΩ potentiometer |
