“Use the Arduino-HomeDing low-code library for ESP8266 to build and configure a sensor device with DHT22 or other environment sensors.
Building an sensor for environment data on the outside can be done easily by using the HomeDing Arduino library, Here many different sensors and other functional elements can be used without hardcore coding by defining elements and actions on the configuration.
This walkthrough about using a simple DHT22 sensor to capture temperature and humidity and you can find other sensor configurations in the linked documentation. A ESP8266 based board is used that allows directly accessing the device by WiFi as there is a built-in Web Server.
Some weather parameters are interesting to be measured by using an outside sensor like
- Sun light
- Air pressure
There are many sensor elements supported by the library and it is easy to used a different sensor or add other sensors as this is just done by configuration.
This project is a good starter project as well to explore the possibilities for building sensors gadgets yourself.
In contrast to the sensor that must be exposed to the outside air the microprocessor board should be placed into a water proof housing. Only the USB power line and the sensor wires are going out.
This sensor should be placed in a location where direct rain and sunlight could not reach it so there is no need for special high water resistant shielding required.
Also USB power is available and the device can be powered all the time.”
