A standard datasheet tells you:
If you cannot find the exact YL105 datasheet, use a multimeter to measure the following in your current circuit: How To Read Electrical Component Datasheets For Projects yl105 datasheet better
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. Unlike the raw DHT11, the YL105 comes pre-soldered
Without this, a user might confidently switch a 6A fridge compressor, only to find the relay contacts welded shut after a month. The better approach is to apply a safety factor of 0.4x the AC rating for inductive loads—a rule of thumb that no cheap datasheet will print. Unlike the raw DHT11
