I2C Pressure Sensor

Category: Tags: , , , , ,

Description

Applied Measurements I2C pressure sensor Pa6DC uses an I2C (Inter-Integrated Circuit) protocol to communicate with the Master Controller.  The I2C output is ideal for OEM, machine feedback systems, control systems and automation applications.

The benefit of using a pressure sensor with an I2C interface is that can be supported along with many I2C devices on the same circuit. I2C protocol allows an unlimited number of master devices to communicate with a maximum of 1008 slave devices on the bus. For example one Master with one Slave, multiple Masters with a single Slave, a single Master with multiple Slaves, or a Multi-Master with multiple Slaves. The I2C gas pressure sensor is designed to work as a Slave on an I2C protocol bus.
