LHT65 Temperature & Humidity sensor 27 / 37
High Power Case:
 Radio Parameter: SF10, 125kHz, 20dbm
 Transmit interval: 15 minutes.
 Payload : 8 Bytes.
To simplify the calculation, we can:
 Combine built-in sensor and E1 sampling energy together to 870ms@2ma
 Combine two RX windows together.
There is a power consumption tool for easy analyze. And below is the analyze result.
Ignore the 11 year, because the battery has a max 2% discharge per year.
