IR Receiver TSOP1738

IR Receiver is a communication IC with a short wavelength.  This is a simple and cheap way for wireless communication form. This is seen in our TV remote while changing the channels. This repeatedly turns ON and OFF for 38,000 times a second to transmit information. IR Receiver TSOP1738 is widely used.

TSOP17XX receives the modulated Infrared waves and changes its output. TSOP is available in many frequencies like TSOP1730, TSOP1738, TSOP1740 etc. Last two digits represent the frequency (in kHz) of modulated IR rays, on which TSOP responds. Like for example, TSOP1738 reacts when it receives the IR radiation modulated at 38Khz. Means it detects the IR which is switching On and Off at the rate of 38Khz. TSOP’s output is active low, means its output remains HIGH when there is no IR and becomes low when it detects IR radiation. TSOP operates on a particular frequency so that other IRs in the environment can’t interfere, except the modulated IR of a particular frequency. It has three pins, Ground, Vs (power), and OUTPUT PIN.
