Find an appropriate library and run the example for the sensor of your choosing. Modify the example to print out comma-separated sensor values over serial at 9600 baud in the following format. The github rep has an example already set up for the environmental combo.
Code Block Serial.print("{\"sensorNameOne\":"); Serial.print(sensorData1); Serial.print(","); Serial.print("\"sensorNameTwo\":"); Serial.print(sensorData2); Serial.print("}"); Serial.println();
On one computer install and run the JsonReciever Processing sketch to record the sensor data to a JSON file.
Take some notes and photos of where you recorded the data. Be careful to name and organise your JSON files!
