LoRaWAN Battery Charge Budget Calculator

Estimate battery autonomy from sleep current and radio transmit events. Adjust every input using measured device values. The example below is illustrative, not a warranty or ATLAS product specification.

Enter your measured inputs to calculate a preliminary daily charge budget. JavaScript is required for automatic results.

Simplified formula: Qdaily = (Isleep/1000) × (24 − N × t/3600) + Itx × N × t/3600, where N = 1440 / reporting interval. Allow additional charge for receive windows, processing, sensor excitation, unsuccessful join attempts, downlinks and ageing.
