Temperature in Leonberg. It is an PIC32MX measuring temperature and pressure with a BMP085. Data logging is done with an ESP8266 interfacing it over the usart interface with AT commands.
self built weather station based on electric imp and sensors bmp280 (temperature, pressure, humidity) and bh1750 (luminosity). Measuring outside and inside. Placed at Campinas, Brazil.
This is the second device that I am building and is based now on BME280
Solar cells connected in a cube-like shape and exposed to the sun. Depending on the time-of-day (solar incidence) the power generated by each cell may be different.
