What is I2C sensor?

The I2C bus is a simple and flexible way to transfer digital data between two electronic devices which may be physically seperate or contained on the same printed circuit board (PCB). The main advantages to an I2C as opposed to other methods of sensor connection is: Only needs 2 wires to connect up to 255 devices.

How does I2C sensor work?

I2C devices exchange bits of data whenever the shared clock signal changes. Controller and peripheral devices both send bits of data when the clock changes from low to high (called the rising edge of the clock). For example, you can set its I2C address, set the sensitivity of the sensor, and so forth.

What is I2C temperature sensor?

The TMP100 and TMP101 are digital temperature sensors optimal for thermal management and thermal protection applications. The TMP100 and TMP101 are I2C and SMBus interface compatible and are specified over a temperature range of -55°C to +125°C. NOTE 2: SCL and SDA require pullup resistors for I2C bus applications.

Is I2C an ultrasonic sensor?

Instead of the common GPIO interface, this version of HC-SR04 uses I2C to communicate with host controller. HC-SR04 ultrasonic sensor provides a very low-cost and easy method of distance measurement.

What is a sensor bus?

Sensor Buses are a subdivision of Industrial “Field Buses”. Sensor buses offer few capabilities and are the lowest grade of existing industrial Field Buses. Sensors require few complex commands and options, while the higher lever Field Buses require more options having more complex operations to perform.

How do I connect my I2C device?

When you connect two devices to each other using the I2C bus, you just need to connect the VCC pin from one device to the VCC pin from the other device, and do the same to the SDA, SCL and GND pins. Well, just look at the pretty picture! One of the devices will assume the role of the Master.

What is MAX30205?

MAX30205 is an accurate temperature sensor with alarm/shutdown/interrupt output.It has a high-resolution sigma-delta ADC (Analog-to-Digital Converter) that converts the temperature data to digital form. It has an operating temperature range of 0-50°C.

What is the range of ultrasonic sensor HC SR04?

2 cm to 400 cm
The HC-SR04 ultrasonic sensor uses SONAR to determine the distance of an object just like the bats do. It offers excellent non-contact range detection with high accuracy and stable readings in an easy-to-use package from 2 cm to 400 cm or 1” to 13 feet.

How is Collision Avoided in a CAN bus?

Logical collisions can be avoided completely by making source node ID a part of arbitration field and enforcing node ID uniqueness. If the messages have different arbitration fields the first node losing arbitration will stop transmitting, allowing the other node to send complete correct message.
