Sensor Interface

The HS300x-MC1 series sensor uses a digital I2C-compatible communication protocol. To accommodate

multiple devices, the protocol uses two bi-directional open-drain lines: the Serial Data Line (SDA) and the Serial

Clock Line (SCL). Pull-up resistors to VDD are required. Several slave devices can share the bus; however only

one master device can be present on the line.

I2C Features and Timing

The HS300x-MC1 series sensor operates as a slave device on the I2C bus with support for 100kHz and 400kHz

bit rates. Each transmission is initiated when the master sends a 0 START bit (S), and the transmission is

terminated when the master sends a 1 STOP bit (P). These bits are only transmitted while the SCL line is HIGH.
