Question

compare infra red sensor and frequency modulation transmitter ​

Answer 1

Answer:

RF, also known as “radio frequency,” and IR, which stands for “Infrared,” are two kinds of energy used in remote controls to communicate commands. ... But if you're curious, the easiest way to tell is if you need to point the remote directly at the device you're trying to control. Your TV remote is IR

Explanation:

Answer 2

Answer:

Frequency Modulation Transmitter:​

• FM or frequency modulation is a type of Transmission that is used to send out radio signals or radio frequencies which are within the range of Spectrum of electromagnetic waves that range from 3 kilohertz to 300,000 megahertz.

Infra Red Sensor:

• While IR transmission for infrared wireless transmission is a range of electromagnetic Radiation whose waves are longer in length than the visible spectrum but is less than the FM or radio waves. So the main difference lies in the length of waves.
