Where to use TSOP-1838 Sensor

 The TSOP sensor has the ability to read the output signals from home remotes like TV remote, Home theatre remote, AC remote etc.. All these remotes will work with a frequency of 38kHz and this IC can pick up any IR signals process them and provide the output on pin 3. So if you are looking for a sensor to analyze, re-create or duplicate the functions of a remote then this IC will be the perfect choice for you.Also keep in mind that this series TSOP-1838 will receive only 38Khz IR signals. How to test and use TSOP1838 Sensor The TSOP-1838 is an IR Receiver Sensor, which can be used to receive IR signals of 38Khz. The sensor operates on 5V and consumes around 5mA to operate. Normally the signal pin IC is connected to a microcontroller to analyse the IR signal received. But let’s consider that you just purchased the IC and you want to check it is working.

TSOP-1838 Applications
  • Receive IR signals
  • Decode Remote signals
  • Analyze, re-create or duplicate remote Signals
  • Wireless control applications
  • Receiver circuit for IR remote controls
  • IR Remote tester circuits
