-The WeatherDuino Transmitter units are a very important part of all system. They not only transmit[([[:​common_questions_weatherduino_system#​how_data_is_transmitted|How data is transmitted]]?​)] all the data to the WeatherDuino receiver, but are also an interface where you will connect all weather instruments that you intend to use.\\ ​ 
-Only one Transmitter unit is enough to build a fully featured WeatherDuino weather station, however you use up to four Transmitter units per system. The main reason why someone may want to use more than one Transmitter unit, is to get a better positioning of the weather instruments,​ per example, use one TX for the weather instruments that usually are placed above the roof, like the anemometer and wind vane, and use another TX for the weather instruments that should be placed near the ground level, like temperature / humidity sensors, rain gauge, or even soil moisture sensors.

 +Only one Transmitter unit is needed to build a fully featured WeatherDuino weather station, however, you can use up to four Transmitter units per system. The main reason why someone may want to use more than one Transmitter unit is to get a better positioning of the weather sensors. For example, one Transmitter may be used for sensors that are usually placed above the roof, like the anemometer and wind vane, and another Transmitter for the sensors that should be placed near the ground level, like temperature / humidity sensors, rain gauge, or even soil moisture sensors.

-A detailed parts list can be downloaded from here: [[http://​www.meteocercal.info/​forum/​attachment.php?​aid=530|WeatherDuino ​Pro2 TX v3.12 Parts List]].\\ +Each WeatherDuino transmitter comprises a single printed circuit board (PCB) approximately 100mm x 60mmThe PCB has two main functionsFirst, it provides an interface to a number of sensors via connectors mounted around two sides of the boardSecond, it provides a radio frequency (RF) link between an Arduino Nano microcontroller and a remote ​WeatherDuino ​receiverTwo RJ45 Ethernet-style sockets provide connections to a rain sensor and an anemometer. Many low-cost wind/rain sensors use these connectors so it is often possible to re-use redundant hardware.

 +Apart from the rain gauge and anemometer, the PCB provides inputs for two analogue sensors (nominally solar radiation & UV), and three digital inputs (two I<​sup>​2</​sup>​C). It also has a 9 volt output which may be turned on and off by the WeatherDuino software. A typical use for this would be to control the fan in an aspirated radiation shield. The PCB has a space for a line driver IC which may be needed if the I<​sup>​2</​sup>​C sensors are not mounted close to the transmitter. It's a good idea to fit a DIL socket in this position so that the IC can be easily fitted ​later if needed.

 +RF communication is provided by a small daughter board located near the SMA aerial socket. Other major components on the PCB are a voltage regulator and a MosFET transistor which controls the external power feed. One very useful feature of the transmitter board is a temperature sensor. Although this is not as accurate as the off-board temperature sensor(s) it does provide an indication of conditions in the transmitter box.
