Hi,
Have you breadboarded this circuit to see if your proposal works.
I am not sure the CR2023 will be able to provide the pulse energy for the NRF when it transmits.
Have you measured the idle current of the NRF.
Features and Specifications
- Lithium Coin Cell
- Nominal Voltage: 3.0 Volts
- Maximum Current: 0.19A
- Non - Rechargeable Disposal battery
- Typical Capacity: 240 mAh @ 20°C 15kΩ Load
- Service Life: ~720 Hrs @20°C 15kΩ Load
- Typical Weight: 3.0 grams (0.10 oz.)
- Operating Temp: -30C to 60C
- Self-Discharge: ~1% / year
What is your project, is the pot going to be the actual sensor or is there another piece of hardware that replaces it ?
