The DHT20 is a humidity and temperature sensor. The sensor has a fixed address of 0x38. It is not known if the address can be changed. The library must be initiated by calling the begin() function.

It's time to keep the hot temperatures outside where they belong. Ashlyn Needham is an expert decor and design writer with 6 years of writing for brands and personal clients. She has been published in ...

We propose and experimentally investigate two distinct power-over-Fiber (PoF) approaches, aiming to remotely power Internet-of-Things (IoT) sensing systems for Industry 4.0 environments. The first ...

This is more of an advice request then an issue. Hope you can help me on that. I developed my application on a dev board with ESP32 WROOM without any issue. I then recompiled it to an esp32-c3 and it ...

Abstract: A substrate-integrated waveguide wireless passive temperature and pressure sensor, featuring an integrated metamaterial structure, has been developed to meet the stringent sensing ...

Abstract: In this paper, the design and experimental results of a resonator-based temperature sensor are presented. The sensor consists of an electrostatically-actuated clamped-clamped microbeam ...
