Datasheet

This kit includes a wind vane ,cup anemometer, and tipping bucket rain gauge, with associated
mounting hardware .These sensors contain no active electronics, instead using sealed magnetic
reed switches and magnets to take measurements. A voltage must be supplied to each
instrument to produce an output.
Assembly
The wind sensor arm mounts on top of the two-piece metal and supports the wind vane and
anemometer. A short cable connects the two win sensors. Plastic clips on the underside of the
arm hold this cable in place. Screws are provided to secure the sensors to the arm. The rain gauge
may be mounted lower on the mast using its own mounting arm and screw, or it may be
mounted independently.
Rain Gauge
雨量计为翻斗式的，每次发生一次翻斗为 0.3mm 的雨量。当雨斗翻转时会造成干簧管的一
次闭合，可通过微处理器中断输入来记录翻斗次数,在 RJ11 水晶头的一端需连接一个电阻电
容，如图所示：
The rain gauge is a self-emptying tipping bucket type. Each 0.2794mm of rain cause one
momentary contact closure that can be recorded with a digital counter or microcontroller
interrupt input. The gauge’s switch is connected to the two center conductors of the attached RJ
11-terminated cable.
Anemometer
杯式风速计测量风速的方法是当磁铁通过开关时关闭触点。风速 0.33m/s 导致开关关闭一次.
风速计将连接到风向计上，与风向计公用 RJ11 电缆，风速计占用 RJ11 水晶头的 2、3 脚。
The cup-type anemometer measures wind speed by closing a contact as a magnet moves past a
switch. A wind speed of 2.4km/h causes the switch to close once per second.
The anemometer switch is connected to the inner two conductors of the RJ 11 cable shared by
