Typical Spec of a device
Frequency Band: 2.4GHz
Data rate: 250 Kbps
Operating voltage 1.8 to 3.6 V
Tx power: 5dBm (3.2mW)
Receiver sensitivity: –98 dBm
Current consumption:
RX - 22 mA, TX - 33 mA, Sleep - <1 µA
Assumptions:
Transaction duration: 3ms
Current consumption, avg: 30mA
No. of measurements: 60 per hour
No. of transactions: 80 per hour
How long a Button Cell would last?
CR2032: ~Typical capacity 225 mAh = 810,000,000 mAms
No. of transactions: 810,000,000 / (30 x 3) = 9,000,000
No. of transactions per day: 80 x 24 = 1,920
Duration of the battery: 9,000,000 / 1,920 = 4,687 days = 12.8 years
