 # Temperature sensor
 
 It uses a [TMP36](https://cloud.hodos.ro/wiki/ha/datasheets/TMP35_36_37.pdf) to read temperature and it is optimised for power consumption.  
-It uses watch dog that wakes every 8s and increments a counter. Once the counter reaches a certain value (e.g. equivalent to 5 mins), it will read and send temperature to the gateway.  
-Every hour the voltage is also read and sent.

+According to the [battery life calculator](https://www.allaboutcircuits.com/tools/battery-lifetime-calculator/), a cell coin battery with a capacity of `240mAh` should last for 
 `~ 3 months (108 days)`, given that:
 - Current consumption of device during sleep is `4.5uA`
-- Device wakes up every `5 mins (12 times/hour)`
+- Device wakes up every `hour`
 - Current consumption of device during wake is `10mA`
 - Duration of wake time is `1000 ms`
