DHT22 operating temperature range and startup documentation

Customer:

I’m a beginner and I think the starter kit should include two printed documents:

  1. A parts list with descriptions

  2. URLs where I can find instructions for each experiment included in the kit

There is so much tutorial content available that it’s difficult to quickly find what you’re currently interested in.

In your product description for the DHT22 temperature sensor, the operating temperature range is not documented (only humidity range is provided). The text states:

“this sensor requires a short warm-up time (must be heated to 40 - 80 degrees) to get a result from it”

and specifications for a similar sensor online show it operates from -40 to +80 °C, which suggests a possible error in your text or incomplete documentation.

Opaska jednog početnika. U setu za početnike mislim da bi trebalo priložiti dvije tiskane informacije 1) popis dijelova u setu s opisom 2) Mjesto (URL) gdje se mogu naci upute za izvođenje pojedinog eksperimenta predviđenog s tim dijelovima. Informacija (tutoriala) svih mogućih vrsta ima toliko da se je zapravo teško na brzinu dokopati one koja nas trenutno zanima. senzora DHT22 (ima samo za vlagu). Tekst koji je kod vas na raspolaganju: " ovaj senzor treba kratko vrijeme zagrijavanja(mora se zagrijati na 40 - 80 stupnjeva) kako biste dobili rezultat s njega" i specifikacija za slični senzor na webu da radi od -40 do +80 C ukazuje na moguću grešku u vašem tekstu, ili njegovu nedorečenost.

Soldered Support:

We’re currently working on improvements to the blog section of the website. The functionality is now set up so you can go directly from the product page to the datasheet and tutorial for that product. Look to the right of the product image.
