Description

The TSOP22.., TSOP48.., TSOP24.. and TSOP44.. series are miniaturized IR receiver modules for infrared remote control systems. A PIN diode and a preamplifier are assembled on lead frame, the epoxy package contains an IR filter. The demodulated output signal can be directly connected to a microprocessor for decoding. The TSOP24.., TSOP44.. series devices are optimized to suppress almost all spurious pulses from Wi-Fi and CFL sources. They may suppress some data signals if continuously transmitted. The TSOP22.., TSOP48.. series devices are provided primarily for compatibility with old AGC2 designs. New designs should prefer the TSOP24.., TSOP44.. series containing the newer AGC4. These components have not been qualified according to automotive specifications.

Features

  • Improved immunity against HF and RF noise
  • Low supply current
  • Photo detector and preamplifier in one package
  • Internal filter for PCM frequency
  • Supply voltage: 2.5 V to 5.5 V
  • Improved immunity against optical noise
  • Insensitive to supply voltage ripple and rnoise

 

Suitable Data Format

This series is designed to suppress spurious output pulses due to noise or disturbance signals. The devices can distinguish data signals from noise due to differences in frequency, burst length, and envelope duty cycle. The data signal should be close to the device’s band-pass center frequency (e.g. 38 kHz) and fulfill the conditions in the table below.

 

When a data signal is applied to the product in the presence of a disturbance, the sensitivity of the receiver is automatically reduced by the AGC to insure that no spurious pulses are present at the receiver’s output. Some examples which are suppressed are:

  • DC light (e.g. from tungsten bulbs sunlight)
  • Continuous signals at any frequency
  • Strongly or weakly modulated patterns from fluorescentlamps with electronic ballasts
  • 2.4 GHz and 5 GHz Wi-Fi

Frequently Asked Questions

What is IR transmitter and receiver?

IR Transmitter and IR Receiver are commonly used to control electronic devices wirelessly, mainly through a remote. TV remotes and AC remotes are the best example of IR transmitters. TV generally consists of TSOP1738 as the IR receiver, which senses modulated IR pulses and convert them into electrical signal.

 

What is TSOP sensor?

Description: The TSOP Sensor is a miniaturized receiver for infrared remote control systems. PIN diode and pre amplifier are assembled on lead frame and the epoxy package is designed as IR filter. The demodulated output signal can directly be decoded by a microprocessor.

 

How do I connect TSOP with Arduino?

Circuit Diagram.Connect the VCC pin of the TSOP sensor module to the 5-volt pin of the Arduino and GND of the TSOP sensor module to the GND pin of the Arduino. Attach the data pin of the TSOP sensor module to the digital 12 pin of the Arduino. Your receiver circuit is ready. Now upload the Arduino code given below.
