PCB and Arduino code available below in this section

Arduino based portable altimeter & weather station with OSRAM Pictiva series OLED display based on BME280 sensor and Atmega 328PU.

The PCB is designed to fit in alternative more accurate sensor suche as MS5611 and SHT31.

It measures accurately:

Temperature, Humidity and barometric pressure and calculates dew point, humidex, altitude, actual air density and absolute humidity.

With built in Li-Po charger and 700mAh Li-Po battery.
