int ShtMeasure(unsigned char mode)
{
	unsigned int 	temp = 0xFFFF;
	unsigned char	checksum;
	unsigned char 	c;

	// Signal start of communications
	transstart();

	// Request measurement
	write_byte(mode);

	// Sensor lowers the data line when measurement
	// is complete. Wait up to 2 seconds for this.
	for (c=0; c<20; c++)
	{
		if (! bit_is_set(SHT_PIN, SHT_DATA))
			break;
		DELAY(1000000/10);
	}

	// Read the measurement
	if (! bit_is_set(SHT_PIN, SHT_DATA))
	{
		temp = read_byte();
		temp = temp << 8;
		temp += read_byte();
		checksum = read_byte();
	}

	return temp;
}

а вот я разбил ее на две:
void ShtMeasure(unsigned char mode)
{
	unsigned char 	c;
	// Signal start of communications
	transstart();

	// Request measurement
	write_byte(mode);

	DELAY(350000);

}

int ShtReadData(void)
{
	unsigned int 	temp = 0xFFFF;
	unsigned char	checksum;

	temp = read_byte();
	temp = temp << 8;
	temp += read_byte();
	checksum = read_byte();

	return temp;
}
