microcontroller with an ACK condition for the sensor to continue sending data. If the sensor does not receive an

ACK from the master after any byte of data, it will not continue sending data.

The sensor will send the temperature value first and then the relative humidity value. After having received the

checksum for the humidity value a NACK and stop condition should be sent (see Table 8).

The I2C master can abort the read transfer with a NACK condition after any data byte if it is not interested in

subsequent data, eg. the CRC byte or the sec ond measurement result, in order to save time.

In case the user needs humidity and temperature data but does not want to process CRC data, it is

recommended to read the two temperature bytes of data with the CRC byte (without proc essing the CRC data);

after having read the two humidity bytes, the read transfer can be aborted with a with a NACK.

No Clock Stretching

When a command without clock stretching has been issued, the sensor responds to a read header with a not

acknowledge (NACK), if no data is present.

Clock Stretching

When a command with clock stretching has been issued, the sensor responds to a read header with an ACK and

subsequently pulls down the SCL line. The SCL line is pulled down until the measurement is complete. As soon

as the measurement is complete, the sensor releases the SCL line and sends the measurement results.
