Temperature is measured in degrees celsius, relative 25*43fbe66dSAndre Wernerhumidity is expressed as a percentage. In the sysfs interface, all values are 26*43fbe66dSAndre Wernerscaled by 1000, i.e. the value for 31.5 degrees celsius is 31500. 27*43fbe66dSAndre Werner 28*43fbe66dSAndre WernerThe device communicates with the I2C protocol. Sensors have the I2C 29*43fbe66dSAndre Werneraddress 0x44 by default. 30*43fbe66dSAndre Werner 31*43fbe66dSAndre Wernersysfs-Interface 32*43fbe66dSAndre Werner--------------- 33*43fbe66dSAndre Werner 34*43fbe66dSAndre Werner=================== ================= 35*43fbe66dSAndre Wernertemp1_input: temperature input 36*43fbe66dSAndre Wernerhumidity1_input: humidity input 37*43fbe66dSAndre Werner=================== ================= 38
