Texas Instruments HDC302x/ HDC302X-Q1 digital humidity sensor

     Texas Instruments HDC302x/ HDC302X-Q1 Digital humidity sensor is an integrated capacitive relative humidity (RH) and temperature sensor. It comes in a compact 2.5mm x 2.5mm package that provides high precision measurements over a wide power range (1.62V to 5.5V) with ultra-low power consumption. The temperature and humidity sensors are 100% tested and adjusted in an NIST-traceable production environment and verified with equipment that complies with ISO/IEC 17025 standards.

     Offset error correction can reduce the offset of the relative humidity sensor due to aging, exposure to extreme operating environments and pollutants, thus bringing the device back to the precision specification. Automatic measurement mode and ALERT features minimize MCU sleep time for battery iot applications, thereby reducing system power consumption. Four different I2C addresses support speeds up to 1MHz. Heating element is provided to dissipate condensation and moisture.

     Texas Instruments HDC3020/HDC3020-Q1 is an open-cavity package with no protective cover. A cover option is available for both device models to protect the open chamber relative humidity sensor (HDC3021/HDC3020-Q1 and HDC3022/HDC3021-Q1). HDC3021/HDC 3021-Q1 features a removable guard strap for conformal coating and PCB rinsing. HDC3022/HDC3022-Q1 has permanent IP67 filter membrane, dustproof and waterproof, and realize PCB washing. HDC 3020-Q1 devices comply with AEC-Q100 standards for automotive applications.
