About Sensors & Interfaces
Sensors and communication interfaces allow electronic systems, robots, and embedded devices to interact with the physical world. Sensors collect information such as distance, motion, temperature, pressure, light, position, and environmental conditions, while interfaces enable devices to exchange data and communicate with each other.
Understanding how sensors work and how devices communicate is essential for robotics, automation, IoT, AI systems, industrial control, and embedded development projects.
Sensors
Measure distance, movement, temperature, light, pressure, and environmental data.
Communication Interfaces
Connect devices using I2C, SPI, UART, CAN Bus, USB, Ethernet, and wireless protocols.
Robotics Integration
Connect sensors to robots, embedded systems, and autonomous platforms.
Data Communication
Transfer information between controllers, computers, and intelligent devices.
Frequently Asked Questions
A sensor is a device that detects and measures physical properties such as temperature,
distance, pressure, motion, light, sound, humidity, or acceleration and converts them into data.
Common robotics sensors include LiDAR, cameras, ultrasonic sensors,
IMUs, GPS receivers, encoders, force sensors, proximity sensors,
and environmental sensors.
I2C (Inter-Integrated Circuit) is a communication protocol that allows multiple devices
to communicate using only two signal wires. It is commonly used for sensors,
displays, and embedded peripherals.
SPI (Serial Peripheral Interface) is a high-speed communication protocol
commonly used for displays, memory devices, sensors, and embedded hardware.
UART (Universal Asynchronous Receiver-Transmitter) is a simple serial communication method
widely used for GPS modules, motor controllers, sensors, and debugging interfaces.
CAN Bus is a robust communication protocol commonly used in robotics,
industrial automation, vehicles, and distributed control systems where reliability is critical.
An IMU (Inertial Measurement Unit) combines accelerometers and gyroscopes
to measure movement, orientation, acceleration, and rotational motion.
LiDAR uses laser pulses to measure distance and generate detailed 2D or 3D maps
of the surrounding environment, making it widely used in robotics and autonomous systems.
Analogue sensors output continuously varying signals,
while digital sensors provide discrete digital values that can often be read directly
through communication interfaces such as I2C or SPI.
Yes. Most microcontrollers and SBCs can support multiple sensors simultaneously
using a combination of GPIO, I2C, SPI, UART, USB, and network interfaces.
The best protocol depends on the application. I2C is popular for sensors,
SPI offers higher speeds, UART is simple and widely supported,
and CAN Bus is preferred for robust industrial and robotics systems.
Yes. RoboSavvy can help you select sensors, communication hardware,
