Anemometer with ESP8266 Ventus W132 and mqtt

Link to buy a Ventus W132: https://amzn.to/3aKWZxz

A ESP-8266 develompent board, which sents sensordata of a Ventus W132 via mqtt e.g. to HomeAssistant sensors:

• wind speed
• wind direction
• wind gust
• temperature
• and huminity to a mqtt-broker

ToDo: connect 3 wires of ESP-8266 direct to the 3 wires of the 433 MHZ-sender it is not neccesary to cut the wires, try to stripp a bit the isolation to soldering the wires of your ESP-8266.

       USB  ------------ USB    
                         3.3V ----------------- red   
                         GND  ----------------- black
                         D7   ----------------- blue

Your W132 does not need the batteries in its battery compartment, the W132 will get his power from the ESP-8266
