 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 so it is often possible to re-use redundant hardware. Each WeatherDuino transmitter comprises a single printed circuit board (PCB) approximately 100mm x 60mm.

 Apart from the rain gauge and anemometer, the PCB provides inputs for two analogue sensors (nominally solar radiation & UV), and three digital inputs (two I2C). 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 I2C 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. Apart from the rain gauge and anemometer, the PCB provides inputs for two analogue sensors (nominally solar radiation & UV), and three digital inputs (two I2C).
