Product Overview
The ENS210 is a relative humidity and temperature sensor with an integrated IC slave interface. Encapsulated in a QFN4 package, it offers ultra-accurate measurements with a temperature sensor accuracy of 0.15C and a relative humidity sensor accuracy of 2.0%RH (typical). It operates across a wide temperature range (-40C to 100C) and humidity range (0% to 100%), with a broad operating voltage of 1.71V to 3.60V. The sensor features a small footprint (2.0mm x 2.0mm x 0.75mm), low power consumption, and provides digital pre-calibrated output directly in %RH and Kelvin. Its high reliability and long-term stability make it suitable for various demanding applications.
