HDC3020QDEFRQ1 General Description

Featuring four different I2C addresses with speeds up to 1 MHz, the HDC302x-Q1 provides flexibility and compatibility with various systems. The optional heating element helps prevent condensation and moisture buildup, ensuring reliable performance in all environments. For added protection, there are two variants with cover options available: HDC3021-Q1 with removable protective tape and HDC3022-Q1 with a permanent IP67 filter membrane. Both options offer additional safeguards against dust, water, and PCB wash, making the sensor suitable for use in harsh conditions
