The infrared receiver is a device that can receive infrared signals and independently complete the output from infrared reception to TTL electrical frequency signal compatibility. It is similar in size to ordinary plastic-encapsulated transistors and is suitable for various infrared remote control and infrared data transmission.
Judge whether the receiver is damaged: use a multimeter to block the DC voltage, connect the black test lead to the receiver ground (GND), and the red test lead to the output terminal (OUT). When there is no signal input, the voltage should be stable at 5V, if the voltage is always at 2~4V Jumping between, the receiver is damaged by leakage, the fault is sometimes the receiving signal and sometimes the signal cannot be received; when pressing the button to transmit the signal, the output voltage should drop to about 3V, and then rise to DC 5V, if the voltage does not drop Keep unchanged, because the receiver does not receive the remote control signal failure. How are the three pins defined? Which pin is GND, which is power +5v, and which is the signal pin. The printing on some receiving boards is also vague. In these situations, teach novices a practical trick. First of all, most receiving boards will have small electrolytic capacitors such as 16v47vf. They are polarized. The positive pole is connected to the +5v of the receiving head, and the negative pole is connected to the GND pin. Then the remaining pin is needless to say the signal pin (sign ) Again.
• Power-On Reset Generator
• Small design
• Built-in dedicated IC
• Wide angle and long distance reception
• Strong anti-interference ability
• Fiber that can withstand environmental interference
• Low voltage operation
• The structure of the infrared receiver has only three external pins: Out, GND, and Vcc. Very convenient to interface with the microcontroller.
- The pulse signal output terminal is directly connected to the IO port of the microcontroller
- GND is connected to the ground wire of the system (0V)
- Connect Vcc to the positive pole of the system's power supply (+5V)
