General Description
Applications
- Portable as Mobile phones and Wearables
- Smart Home and Building Automation (e.g. HVAC, Air puriers, Smart
Thermostats, Wireless Sensor nodes)
- Home Appliance (e.g. Dryers, Refrigerators, Microwaves)
- Weather stations
- Printers, Enterprise drivers and Server Rooms
- Medical baby incubators
The new digital ENS210 is the ams accurate relative humidity and temperature sensor
ideal for space- and power-constrained designs such as portable and connected smart
home devices and appliances. ENS210 delivers an optimized combination of Relative
Humidity and Temperature sensing accuracy, ultra-low power consumption and small
size. The ENS210 comes pre-calibrated and ready-to-use, thereby accelerating customer
time-to-market while lowering the overall bill of materials (BOM).
The device is encapsulated in a QFN4 package and includes a I
2
C slave interface for
communication with a master processor. ENS210 oers a wide voltage range of
1.71V to 3.6V. The monolithic integration in plain CMOS technology allows for an
ultra-low power consumption in standby and active mode. An always-on domain allows
the sensor to listen to the master device even in standby mode. The sensor returns the
relative humidity in % RH and the temperature in Kelvin.
Seamless design-in by availability of a full collaterals set, including datasheet, applica-
tion notes, SW drivers and regional eld application engineering support. The ENS210
is optionally available in combination with SW compensation engine for quick and
accurate RH & T prediction in portable applications, and proprietary ams algorithms for
accurate air quality measurement.
