# AM2302/DHT22 Example This example demonstrates how to read the temperature and humidity by using the [am2302_rmt](https://components.espressif.com/component/suda-morris/am2302_rmt) library. ## How to Use Example ### Hardware Required * A development board with Espressif SoC * A USB cable for Power supply and programming * AM2302/DHT22 sensor ### Configure the Example Before project configuration and build, be sure to set the correct chip target using `idf.py set-target <chip_name>`. Then assign the proper GPIO in the [source file](main/am2302_example_main.c). ### Build and Flash Run `idf.py -p PORT build flash monitor` to build, flash and monitor the project. (To exit the serial monitor, type ``Ctrl-]``.) See the [Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html) for full steps to configure and use ESP-IDF to build projects. ## Example Output ```text I (314) main_task: Started on CPU0 I (324) main_task: Calling app_main() I (324) gpio: GPIO[2]| InputEn: 1| OutputEn: 0| OpenDrain: 0| Pullup: 1| Pulldown: 0| Intr:0 I (334) gpio: GPIO[2]| InputEn: 1| OutputEn: 1| OpenDrain: 1| Pullup: 1| Pulldown: 0| Intr:0 I (344) example: Start reading temperature and humidity from AM2302 sensor I (2384) example: Temperature: 29.2 °C, Humidity: 89.3 % I (4414) example: Temperature: 29.2 °C, Humidity: 88.1 % ```
