USB TnH SHT10 TypeA 160
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.

The sensor PCB has re-layout and fit into a USB Dongle plastic case.


Operating Temperature (CPU): -20°C ~ +70°C
Connection to PC: USB (CDC Virtual COM port)
Power: USB Powered
Temperature Accuracy: +/-0.5°C at 25°C (max +/-3°C at 120°C)
Temperature Resolution: 14bits
Temperature Range: -40°C to 120°C
Humidity Accuracy: +/-4.5 %RH
Humidity Resolution: 12bits
Humidity Range: 5 %RH - 95 %RH
