Additionally, the sensor achieves a high sensitivity of 10.3 $\mu$ A/%RH, confirming its suitability for humidity-based breath detection applications in wearable and health-monitoring systems.

Abstract: This paper describes printed resonant structures on a flexible substrate for humidity detection. The devices consist of a screen-printed spiral inductor working as radio frequency ...

This repository contains a complete ESP32-based IoT project that reads temperature and humidity from a DHT22 sensor, displays the values on an LCD1602 (via I²C), publishes the data to the Arduino IoT ...
