The patented use of industry-standard, low-K polymeric dielectrics for sensing humidity enables the construction of low- power, monolithic CMOS Sensor ICs with low drift and hysteresis, and excellent long term stability. The humidity and temperature sensors are factory-calibrated and the calibration data is stored in the on-chip non- volatile memory. This ensures that the sensors are fully interchangeable, with no recalibration or software changes required The TH06 is reflow solderable. It can be used as a hardware- and software-compatible drop-in upgrade for existing RH/ temperature sensors , featuring precision sensing over a wider range and lower power consumption. The optional factory-installed cover offers a low profile, convenient means of protecting the sensor during assembly (e.g., reflow soldering) and throughout the life of the product, excluding liquids (hydrophobic/oleophobic) and particulates. The TH06 offers an accurate, low-power, factory-calibrated digital solution ideal for measuring humidity, dew-point, and temperature, in applications ranging from HVAC/R and asset tracking to industrial and consumer platforms.

Typical values measured at 25 C. 3. Occurs once during powerup. Duration is <5 msec. 2 4. Occurs during I C commands for Reset, Read/Write User Registers, Read EID, and Read Firmware Version. Duration is 2 <100 s when I C clock speed is >100 kHz (>200 kHz for 2-byte commands). 2 5. IDD after a user register write. Initiating any other subsequent I C transaction on the same bus (such as the user 2 register read, starting an RH measurement, or traffic directed at other I C devices) will transition the device to standby mode. 6.
