Yl105 Datasheet Better ((link)) -

The YL-105 is an RF device; it needs an antenna to work properly. Most

The standard module includes a comparator (LM393) for digital output. Throw that away. The potentiometer drifts with temperature. yl105 datasheet better

If you read the YL105 faster than 1 Hz (e.g., every 500ms), the internal thermistor will self-heat by 2-3°C. The datasheet does not warn about this clearly. Limit reads to once every 2 seconds for temperature accuracy, even if humidity can refresh faster. The YL-105 is an RF device; it needs

AMS1117-3.3V (converts 5V to stable 3.3V for the radio). Pinout: VCC/GND: Power input. CE/CSN: Digital control pins. SCK/MOSI/MISO: SPI communication interface. Feature: Includes a female header specifically for the nRF24L01+ module Go to product viewer dialog for this item. , eliminating the need for complex wiring.
