Weather Station

Description:

This listing includes: 1 unit of weather station.

- It will measure: temperature, humidity, rain volume, wind speed, wind direction, light, air pressure.

- With RS485 port (it is RS485-UART, not Modbus)

- With cable: 4 wires cable, length: 10 meter

- Including 1 unit of Adaptor (RS485 to USB) (convenient to connect to computer)

- No display for it

- Communication protocol will be provided.

Application: it is suitable for the customers to collect the data from the weather station through
the cable by their own designed software, to their own server(computer).

Attention: Before order, please ensure you know how to develop the software to collect the data. What
we can support only is to provide the communication protocol to you.

Connect to USB connector (4 wire cable)：

Black wire： GND

Red wire： USB A (D+)

Yellow wire： USB B (D-)

Green wire： VDD (4.5V -6V)
