In the kit Simple Sensitive Remote Tester USING T-SOP handy gadget for testing of infrared (IR) based remote control transmitters used for TVs and VCRs etc. The IR signals from a remote control transmitter are sensed by the IR sensor module in the tester. This in turn switches the led. In this idea we can simply test our remote easily. In the kit Simple Sensitive Remote Tester using T-SOP the first block is power supply in which the input is 230V AC which is step down using the transformer (12-0-12) .The 12V ac input is fed to the bridge diode to gives 12V pulsating DC. This DC voltage is filtered through the capacitor to remove the ripples. The filtered DC is fed to 7805 regulator to fetch +5v regulated output.

In the kit Simple Sensitive Remote Tester USING T-SOP 38 kHz infrared (IR) rays generated by the remote control are received by IR receiver module TSOP1738 of the circuit shown in figure 1. Pin 1 of TSOP1738 is connected to ground, pin 3 is connected to the power supply through resistor R4 (100E) and the output is taken from pin 2. The output signal coming from TSHOP pin no 2 is fed to the base of BC548 which is amplified by transistor (BC548).The amplified signal is fed to clock pin 14 of decade counter IC CD4017 from the collector of BC548. Pin 8 of IC CD4017 is grounded, pin 16 is connected to Vcc and pin 3 is connected to LED (red) D2 through R3 (330E), which glows to indicate that the appliance is ‘off.’ The output of IC CD4017 is taken from its pin 2. Second (green) D2 connected to pin 2 through R2 (330E) is used to indicate the ‘on’ state of the appliance. If this system operates the indication means remote is fine enough.
