Digital pressure sensor I2C, piezoresistive, 0-1000 barg
Digital Pressure Sensor can transfer the measurement signals of pressure and liquid level to I2C digital output. With the fast and accurate interface, the 319-I2C is used to build an Internet of Things using a microcontroller. It can read data and control power on and off to reduce power consumption through microprocessor operation.
319-I2C Digital Pressure Sensor is available ranges from -100KPa to 100MPa.
Technical parameters
Remarks: Range -100KPa~100MPa; *The typical value of 0~10KPa and 0~20KPa's zero; temperature drift and sensitivity temperature drift is 0.4%FS@25ºC, max value is 1.6%FS@25ºC
Standard range
Notes: G for Gauge pressure; A for Absolute pressure; D for Differential pressure; S for Sealed gauge.
Data Measurement & Communication Sequence
For read and write operations, the master device commands to start, and sends an ACK (acknowledgement) as a slave device to indicate success. The factory address of the slave device is 0x28, and the communication sequence is shown as below
