In need of detail protocol specification and time sequence, ‘I2C programming guide’ could be
provided by contacting Sales Rep.
※ Caution
1. Please hold only ‘PCB’ of sensor without holding Cavity directly to avoid the physical shock on
sensor. Rough handling or Transportation could result in inaccurate reading.
2. Proper ESD protection during handling is important to avoid electrostatic defect occurrence.
The storage of sensor should be insulated as well
