I have been preparing the receiver using WS-RX-02 receiver and arduino Uno R3 board. My connections are as follows. 3 GND PINS on RECEIVE UNITS are Connected to GND of ARDUINO 2 VCC PINS on RECEIVER UNITS are Connected to 5V on arduino Data Pin on RECEIVER is connected to PIN 3 on arduino. I have connected a simple wire of lenght 17cm as antenna on receiver unit. I am using RCSwitch library to receive signal I am using my laptop to power the arduino. I am trying to capture signals from one of my RF remote. My receiver unit receives the singal only when I bring my remote very very close (about 4 to 5 cm close) to the Receiver unit. If i move it away then signals are not received by my receiver connected to arduino.
Why is my receiver range so short. How can i overcome the problem. Please help.
