Which protocol is used by proximity sensor?(a) I2C(b) SPI(c) UART/USART(d) CANI got this question in an interview for internship.I would like to ask this question from Proximity Sensor topic in portion Sensors of IOT

Answer»

The correct choice is (a) I2C

To EXPLAIN I would say: Microcontroller COMMUNICATION is via standard I2C, where the HOST can set measurement parameters and request results. If desired, programmable threshold allow the VCNL4100 to INTERRUPT the host once threshold values are crossed, thereby minimizing device polling.
