 USB-TnH (SHT10) is a USB temperature + humidity sensor. The temperature and humidity are read by simple ASCII commands via the CDC Virtual Serial port (Atmel). It make the programming more simple compare with other USB communication method. Version 2 has released, it is using another USB PID, please donwload the new Windows Driver asf-sign-inf.zip. You can install this driver to Win8. |
