Для этого нам понадобится:
Датчик температуры и влажности BMP180: http://ali.pub/1al5x8
Но лучше BMP080 : http://ali.pub/1al666
Ethernet Shield W5100 : http://ali.pub/1al6dr
Arduino uno: http://ali.ski/gC_mOa
Схема подключения датчика:
Датчик BMP180 подключается по шине i2c.
SCL – A5
SDA – A4
VCC – 5v
GND – GND
