C.5 Digital I2C Sensor Interface
The I2C Digital interface provides complete integration, which gives the user serial
communications with different implemented sensors with I2C technology, which has become the
standard for simple communications inside equipment, machinery and sensors. The
Datalog
X-PRO Digital I2C interface acquires this digital signals and sends them to the Internet for
subsequent analysis.
