Which sensor detects metal objects without making physical contact?

Inductive Sensor (LJ12A3-4-Z/BX)

You are designing a robot that navigates indoor spaces and must avoid both walls and people. Which combination of sensors is MOST appropriate for this task?

IR Obstacle Avoidance and PIR Motion Sensor

A robot must sort metallic and plastic objects on a conveyor belt. Which sensors should be paired to accomplish this task efficiently?

Inductive and Capacitive Proximity Sensors

What is the PRIMARY reason analog sensors are chosen over digital ones in environmental monitoring applications?

Analog sensors provide continuous and detailed readings

Digital sensors require fewer wires

Digital sensors are not compatible with microcontrollers
