Remote Control Tester using TSOP 1738 | 8,161 view(s)
This Remote Control Tester using TSOP 1738 circuit is very efective to test the remote control which is still function or not, and will be tested by using Infra Red, for example remote control for TV, Radio, AC, etc.
How it works
When the sensor of infra red received the signal, pin 2 will give the output of voltage, this voltage will drive the PNP transistor so that, the LED lamp and disk piezzo will active. For the source power, can be used the 9V battery.
Components
- Transistor BC557
- TSOP 1738 Sensor Infra Red
- R1 = 10k ohm ¼ watt
- R2 = 1k ohm ¼ watt
- R3 = 1k ohm ¼ watt
- BZ = piezzo disk
