We’re making a dashboard showing data from multiple sensors (sensor.community and others) and were wondering whether all sensors send data at the same time and frequency
By default, sensors using airrohr firmware sent data every 145 sec, but this can be changed by the user. Statistically sensor data will be received by the API server spread over time, not all sensors can sent at the same time, nor will the server be able to receive all this at the same time. Look at the time information in your sensors historical files at archive.sensor.community for more information.
I will investigate.
