DTH21 on esp01.....no reading at 0°c
Posted: Sun Feb 19, 2017 3:01 amHi.
My Esp01 start, connect to router and mqtt, read temperature and humidity from dth21, than goes to sleep for 10min, but stop working at 0°C. Esp and sensor are powering from LiIon battery. Everything work OK until temperatures drops, then mqtt server does not become data any more.
When it gets warmer esp start sending data again.
Any ideam
