I was recently given the sensor components from an old La Cross WS-2310 weather station (link for reference), including a wind speed and direction sensor, and a rain sensor. I am attempting to hook these components into my existing ESP32-based weather station, which includes a BME280 environmental sensor and soil moisture sensor. The rain sensor is a tipping bucket type sensing via a simple magnetic reed switch, which is easy enough to connect to the ESP. The wind speed and direction sensor is more complex, however, and I am having trouble “hacking” it to work with my system. Here is a picture of the circuit board inside the sensor:
I am assuming the pin labels reference the four wires that go out to the original RJ11 cable. I have tried connecting to a USB-UART device to read serial data from the Serial O/P (output?) pin with a little voltage going to “VDD” and GND to ground, but nothing showed up in my serial monitor. I am not sure what “regulator CE” means. These four wires must send wind speed and direction from the two sensors, but I am not sure how it works. This looks more complex than the reed-based wind sensors that I am familiar with, and I am wondering if anyone could lend some help hacking this thing and getting it working with my setup. Thanks!
