+ | 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. | ||

+ | Each WeatherDuino transmitter comprises a single printed circuit board (PCB) approximately 100mm x 60mm. The PCB has two main functions. First, it provides an interface to a number of sensors via connectors mounted around two sides of the board. Second, it provides a radio frequency (RF) link between an Arduino Nano microcontroller and a remote WeatherDuino receiver. Two RJ45 Ethernet-style sockets provide connections to a rain sensor and an anemometer. Many low-cost wind/rain sensors use these connectors but beware that not all use the same pin arrangement. | ||

+ | 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< | ||

+ | 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. | ||
