In this channel, the measurements of my weather station are visualized. The following sensors are
used: DHT22, BMP180, WH14C. The measurements are taken every six minutes. Then, they are send to this ThingSpeak channel by the Raspberry Pi Zero.
Arduino Pro Mini (3.3 V, 8 MHz) measuring outside temperature and humidity using a DHT21.
Powered by 3 AA eneloops using (only) the on-board voltage regulator.
Battery voltage is measured by internal ADC.
