ENS210
Relative Humidity and Temperature
Sensor with I²C Interface
General Description
The ENS210 integrates one relative humidity sensor and one
high-accuracy temperature sensor. The device is encapsulated
in a QFN4 package and includes an I²C slave interface for
communication with a master processor.
Ordering Information and Content Guide appear at end of
datasheet.

ENS210 − GeneralDescription
Applications
The ENS210 applications include:
Portable devices for personal health and wellness
Air cleaners, air purifiers and smart thermostats
Weather stations
Home appliances, such as washing machines, dishwasher,
and dryers
Baby monitoring devices
Transportation condition monitoring
Block Diagram
The internal block diagram of ENS210 is shown in Figure 2.
The I²C (communication) interface is connected to a controller
which acts as the command interpreter and as bus master of
the internal Advanced Peripheral Bus (APB). The memory and
sensors are slaves of the APB. The MTP memory is used to store
the sensor calibration parameters and unique ID.
To reduce power consumption the controller only powers the
measurement engine when needed.
