How to Use This Calculator
- Enter your battery capacity in mAh (e.g., AA = 2500 mAh, CR2032 = 225 mAh).
- Set active current (mA) during sensor reading and sleep current (uA) in deep-sleep mode.
- Enter wake time per cycle in seconds and the full cycle period in seconds.
- Input TX current (mA) and TX duration (ms) for your radio technology (BLE, LoRa, WiFi).
- Review Battery life in days, months, and years alongside the Duty cycle percentage.
- Reduce cycle period or TX duration if battery life is too short for your deployment target.
