Power and Memory Calculations Form

Three-Channel Dataloggers with Sensors

To use this form, first select values for Sensor Type (the type automatically includes whether sensors are Passive or Active), DAS Type (Quanterra or Reftek), and use of Telemetry.
Then, specify the Battery capacity in Amp-Hours, and the Solar Panel Wattage (watts), and then click the 'Estimate' button.
If you simply want to check memory usage, ignore the sensor, datalogger, telemetry, and battery/solar power options - just enter DAS memory, sample rate, data format, and number of channels, then click 'Estimate' to go.

which will hold many GBs
