Yl105 Datasheet Better Here

This article breaks down the YL105 datasheet in detail and explains exactly where, why, and how this sensor is than its more famous rivals. Part 1: What is the YL105? (A Datasheet Overview) Before we discuss "better," we need a baseline. The YL105 is a digital temperature and humidity sensor module. Unlike the raw DHT11, the YL105 comes pre-soldered onto a PCB with a built-in pull-up resistor and a filtering capacitor. Key Specifications from the YL105 Datasheet: | Parameter | Value | Why it matters | | :--- | :--- | :--- | | Operating Voltage | 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 |
