Do'a Sedang Belajar

اَللَّهُمَّ افْتَحْ عَلَيْنَا فُتُوْحَ ﭐلعَارِفِيْنَ وَارْزُقْنَا فَهْمَ النَّبِيِّـيْنَ وَإِلْهَامَ ﭐلمَلاَئِكَةِ المُقَرَّبِيْنَ بِرَحْمَتِكَ يَآ 

أَرْحَمَ الرَّاحمِيِْنَ

“ Ya Allah, bukakanlah pintu hati kami sebagaimana orang-orang yang arif , Kurniakanlah kepada kami kefahaman Nabi-Nabi dan ilham para Malaikat yang hampir dengan-Mu, dengan Rahmat-Mu Wahai Tuhan Yang Maha Pemurah Lagi Maha Penyayang. ”

Hmm, its time to fulfill my progress report but i just wondering about something.

I still confuse what is the different of transducer, sensor and actuator.

Let's figure out to improve your understanding.

TRANSDUCER 

is a device that transform signal from one form to another form. 

It can be classified into energy converter.

SENSOR

is a device that detect and respond inputs from the physical environment. 

Some inputs are light, heat, motion, moisture, gas, pressure and etc.

The respond or output of the sensor usually is electrical signal. 

ACTUATOR 

is opposite of sensor, which convert electrical signal into physical output. 

Interesting fact

- All sensors are transducer but not all transducer is sensor.

- Sensor and actuator are type of transducer. Normally, sensor being an input and actuator being an output.

ok, now i understood.
