Weather HAT PRO (Assembled) for Raspberry Pi

This version of the Raspberry Pi Weather HAT ships pre-assembled with no soldering required – the easiest way to get started monitoring the weather with the Raspberry Pi! This board is similar to our original Raspberry Pi Weather Board but features an integrated BME280 pressure/temperature/humidity sensor, so no need to add this on after the fact. It still features the same 4-channel AS1015 Analog to Digital Converter, and RJ11 connection points for the SparkFun Weather Meters. Simply plug in the SparkFun Weather Meters and you will have Wind Speed, Direction, and Rainfall in addition to the onboard Humidity, Barometric Pressure, and Temperature.

If you are feeling a little more adventurous, additional connection points are available for an external fan, DS18B20 Temperature Sensor (with onboard pull-up resistor), a servo motor, extra analogue inputs, and an external 5V source. These extra connections require minor soldering, but nothing too challenging!

The 3 extra analogue inputs are now routed to an easy-to-use 2.54mm/0.100” pitch header for connecting additional analogue sensors. The integrated pullup resistors for these three inputs are now optionally connected via a solder jumper. These extra analogue inputs could be connected to a thermistor, soil moisture sensor, or even a simple CDS photocell to provide additional data from your weather station!

The temperature and humidity readings of the BME280 are affected by their close proximity to the Raspberry Pi so we have added a 2-pin header for an external fan. Drawing in external air with a small fan will drastically improve your readings without exposing the sensor to the harsh elements (and keep your Pi running cooler). We recommend this 5V DC Cooling Fan and a JST XH 2 Pin Header.

Finally, we have also added an external input for regulated 5V power. If you are using an external regulator and need an easy way to feed power into the board and the Pi – add a two-pin connector of your choice and you are good to go!

The board is also compatible with all 40-pin GPIO versions of the Raspberry Pi. Raspberry Pi Sold Separately.
