About This Project
Weather Station 2019 is a device to monitor temperature and humidity, that sends all the results to the
Cayenne server with LoRa radio modulation. Weather Station 2019 is built around an Arduino MKRWAN
It’s powered by an Ansmann 3.7V 5200mAh battery connected to Microchip MIC5201 3,3V fixed voltage regulator
in order to guarantee low quiescent currents.
The chosen sensor is I2C interface version of SENSIRION SHT35-DIS. It has a
resolution of ± 0.1% ° C and ± 1.5% RH. SHT35-DIS consumptions are 45μA in idle
state and 6mA in measurement. It’s assembled on a special PCB and placed into
Weather Station 2019 is wired inside an Hammond’s Polycarbonate box with 160x90x60,5mm dimensions
and IP66 protection’s degree.
