The YL-105 is a designed for short-to-medium range data transmission. It typically operates on the 433 MHz frequency band (though variations exist, always check the crystal oscillator on the board). yl105 datasheet better
The YL105 datasheet reveals a 100nF decoupling capacitor on the power rails. The standard DHT11 module (the blue 3-pin version) often lacks sufficient capacitance. This means: void loop() // Moving average filter (removes 60Hz
Always refer to the manufacturer’s YL105 datasheet V1.2 for absolute maximum ratings (TMV: -20°C storage, 5.5V absolute max input). The standard DHT11 module (the blue 3-pin version)
This is where the YL-105 shines. Instead of a binary "Wet/Dry," the AO pin gives you a spectrum (usually 0-1023 on a 10-bit ADC).
Searching "yl105 datasheet better" usually means you want a replacement. Let’s compare it to two superior sensors.
