MEAS HTU21D SENSOR FOR
GROVE SYSTEM
Digital Humidity and Temperature Sensor
The HTU21D provides the necessary hardware to interface the
HTU21D digital relative humidity and temperature sensor to any system
that utilizes Grove compatible expansion ports configurable for I
2
C
communication. The HTU21D sensor is a self-contained humidity and
temperature sensor that is fully calibrated during manufacturing. The
sensor module works in 5V external, and the sensor has selectable
resolution, low battery detection, and checksum capability. The
HTU21D has a low power stand-by mode for power-sensitive
applications.

MEAS HTU21D FOR GROVE SYSTEM
Digital Humidity and Temperature Sensor
Detailed Description
I
2
C Interface:
The HTU21D Grove compliant module can interface to the host in I
2
C model with 5V supply, it has a Grove compatible four
pins port connector configured for I
2
C.
External Control Signals 5V supply:
The IC operates as an I
2
C slave using the standard 2-wire I
2
C connection scheme. As IC is power rated at 3.6V, the board
integrates necessary fixture such as a regulator and electrical level shift so that the SCL and SDA signals could be driven
directly from an external 5V I2C lines and power supply.
