Top 4 Stm32 , Arduino and Raspberry Pi Sensors

 May be you are new in embedded system world , this article will help you to know the most popular sensors that you can use in your projects . these sensors are very helpful and can give you many ideas of robotic projects .

1.Line follower module
Line follower module based on the optical reflector TCRT5000 and LM393 amplifier. It connects to a digital input of an Arduino or compatible card. it is very useful for Robots and you can use it also on analog mode .

 

2. Ultrasonic sensor 

 If you are building an autonomous robot you should have this sensor . it is super easy to use with just 3 pins. 5V, GND and Signal. The effective range is from about 2 centimeters to 300 centimeters . you can find HERE an article about it .

3. Motion sensor 

A motion detector is a device that detects moving objects, particularly people. A motion detector is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area. Motion detectors form a vital component of security, automated lighting control, home control, energy efficiency, and other useful systems.

 

4. Flex sensor
When you need to detect a flex, a flex sensor is the most helpful part for you. As the sensor is flexed, the resistance across the sensor increases. It is great for detecting how much fingers are bent . 

Here is simple example of uses :
