USB-TnH (SHT30)
The USB-TnH (SHT30) is an advanced USB temperature and humidity sensor. Its measurement results can be easily accessed through simple ASCII commands via the CDC Virtual Serial Port, simplifying programming compared to other USB communication methods.
The carefully designed 3D-printed case ensures optimal performance by isolating the sensor chip from the MCU. Additionally, the large air gap around the sensor allows for maximum exposure to the ambient environment, enhancing the accuracy and reliability of the measurements.
