The sensor uses the I2C standard for digital communication with a slave address specified in the Nomenclature and Order Guide in Figure 2. Following sensor power-up, each of the first two read sequences shown in Figure 7 will respond with 2 bytes of the unique 4-byte Serial Number. The first read after power-up will respond with the two most significant bytes of the Serial Number, while the second read will respond with the two least significant bytes of the Serial Number. For reliable performance, allow sensor to be powered for the sensor startup time before performing the first read, then allow a 10 ms command response time before performing the second read.

Read requests taken faster than the Response Time (1 ms) are not guaranteed to return fresh data. The first two bits of each flow reading will be ‘00’, while non-flow responses (such as error and status codes) will begin with ‘11’. There are several user commands available as shown in Table 8. Following an I2C write sequence of a user command, the sensor will respond to the next I2C read request with a 16-bit response. Possible responses to user commands can be seen in Table 9. Table 8.

Therefore, if the pull-up resistors are biased by VDD, and if VDD reaches the maximum supply voltage of 6 V, then the pull-up resistors for SCL and SDA must be greater than 3.0 kOhm to limit the sink current to 2 mA. The typical value for SCL and SDA pull-up resistors is 4.7 kOhm (this value depends on the bus capacitance and the bus speed). 8 Sensing and Internet of Things
