Elements of Mechatronics—Electromechanical
• Electromechanical elements refer to:
– Sensors
• A variety of physical variables can be measured using sensors, e.g., light using photo-resistor, level and displacement using potentiometer, direction/tilt using magnetic sensor, sound using microphone, stress and pressure using strain gauge, touch using micro-switch, temperature using thermistor, and humidity using conductivity sensor
– Actuators
• DC servomotor, stepper motor, relay, solenoid, speaker, light emitting diode (LED), shape memory alloy, electromagnet, and pump apply commanded action on the physical process
• IC-based sensors and actuators (digital-compass, -potentiometer, etc.).


Mexatronikaning elektromexanik elementlari
Mexanik qurilma zvenolari harakatini ishchi organning zarur harakatlariga aylantirishga mo`ljallangan.
Elektromexanik elementlar quyidagilardan iborat:
-Aktuatorlar (ijrochi mexanizmlar)

• 
  servodvigatel, qadamli dvigatel, rele, dinamik, svetodiod (LED), elektromagnit, tormoz, mufta mexanik jarayonlarni bajarish uchun xizmat qiladi.
  

- Datchiklar (Sensorlar)

• 
  Fizik o`zgaruvchilarni datchiklar yordamida o`lchash mumkin, masalan, yorug’likni fotorezistorlar bilan, sath va siljishni potentsiometr bilan, harakat/og’ishni magnitli datchik bilan, ovozni mikrofon yordamida, kuchlanish va bosimni tenzodatchik bilan, temperaturani termistor bilan, namlikni vlagomer bilan va h.k.
  
• 
  Sensorlar tashqi muhit va ishlar ob`ekti hamda menxanik qurilmalar va yuritmalar haqidagi haqiqiy ma`lumotlarni yig’ish va ularni kompyuter boshqarish tizimiga yuborish uchun xizmat qiladi.
