This WeatherHAT is a fully assembled, shrunk-down version, of our original Raspberry Pi WeatherHAT specifically designed for the Raspberry Pi Zero family of single-board computers. The board ships fully assembled with no soldering required and allows you to make a small form factor weather station while retaining all of the remote management abilities of the Raspberry Pi.
Onboard we use 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. Adding additional sensors is a breeze – a Qwiic connector is available to connect a BME series Temperature / Pressure / Humidity sensor (or any other Qwiic compatible sensors or modules you wish to add!) A two-pin JST connector is available for an optional 5V fan for additional airflow while a 3 Pin Screw Terminal is available for a DS18B20 temperature sensor. The DS18B20 connection has the required pull-up resistor already installed.
In this version, we have also added a few optional connection points for additional sensors and other devices. A two-pin connection for a 10K thermistor is available if you prefer to use it for an additional temperature reading. A second two-pin connection is available for a CDS Photocell / Photoresistor. These are ideal if you want to monitor ambient light levels. A three-pin header is available to connect a servo motor – ideal if you want to use a camera and move it. Finally, there is also a 5V input – ideal if you don’t want to use the micro USB connection to power your weather station.
