SHT21

The SHT21 is a digital humidity and temperature sensor made by Sensirion. This repository contains a Java-based library for communication with such a SHT21 sensor. The code is based on the exemplary sample code on Sensirions home page

Supported operations:

• Temperature and humidity measurements.
• Retrieve resolution for temperature and humidity measurements.
• Retrieve status of the end-of-battery alert.
• Retrieve the heater status.

Usage

To use this library, you have to specify the I2C address of the SHT21 sensor. After this you can poll measurements for temperature and relative humidity:

int I2C_ADDRESS = 0x40;

SHT21 sht21 = SHT21Impl.create(I2CBus.BUS_1, I2C_ADDRESS);

Measurement measurement_1 = sht21.measurePoll(MeasureType.HUMIDITY);

Measurement measurement_2 = sht21.measurePoll(MeasureType.TEMPERATURE);
