SI7005-B-GM

SI7005-B-GM is a Si7005 digital relative temperature/humidity sensor. This monolithic CMOS IC integrates temperature and humidity sensor elements, an analogue-to-digital converter, signal processing, calibration data, and an I2C host interface. The patented use of industry-standard, low-K polymeric dielectrics for sensing humidity enables the construction of a low-power, monolithic CMOS sensor IC with low drift and hysteresis and excellent long-term stability. It is factory-calibrated and the calibration data is stored in the on-chip non-volatile memory. This ensures that the sensor is fully interchangeable, with no recalibration or software changes required. Typical applications are Industrial HVAC/R, thermostats/humidistats, respiratory therapy, white goods, micro-environments/data centres, automotive climate control and de-fogging, asset and goods tracking.
