Pinout and Connections

WL101 Superheterodyne Receiver Pinout

The WL101 receiver module features six pins for power, ground, data output, and antenna connection. Refer to the diagram below for pin identification.

คำอธิบายภาพ: A green circuit board showing the WL101 receiver module. Six pins are labeled 1 through 6. Pin 1 is ANT (Antenna), Pin 2 is GND (Power ground), Pin 3 is VIN(VDD) (Power input), Pin 4 is DO(DATA) (Data output), Pin 5 is DO(DATA) (Data output), and Pin 6 is GND (Power ground).

WL102 Transmitter Pinout

The WL102 transmitter module has pins for power, ground, data input, and antenna. Note that the EN (Enable) pin is internally connected to the power supply and has no external function.

The receiver's VDD pin is connected to Arduino's 5V, GND to GND, and one of the DO(DATA) pins to a digital input pin (e.g., D2) on the Arduino. The antenna is shown connected to the ANT pin.

การตั้งค่า

การเชื่อมต่อเสาอากาศ

For optimal performance, connect the supplied helical antenna to the ANT pin of the WL101 receiver and the OUT pin of the WL102 transmitter. The length of the antenna is critical for 433MHz operation; a quarter-wavelength antenna (approximately 17.3 cm or 6.8 inches for 433MHz) is recommended for best range, though the provided coiled antennas are suitable for shorter distances.

แหล่งจ่ายไฟ

• WL101 Receiver: Connect the VIN(VDD) pin to a stable power source (e.g., 5V from Arduino) and GND to ground.
• WL102 Transmitter: Connect the '+' pin to a stable power source (e.g., 3.3V to 12V, depending on desired range and power) and '-' to ground.

การเชื่อมต่อข้อมูล

• WL101 Receiver: Connect one of the DO(DATA) pins to a digital input pin on your microcontroller (e.g., Arduino).
• WL102 Transmitter: Connect the DAT pin to a digital output pin on your microcontroller.

คำแนะนำการใช้งาน

หลักการทำงานพื้นฐาน

The WL102 transmitter sends data using Amplitude Shift Keying (ASK) or On-Off Keying (OOK) modulation at 433MHz. The WL101 superheterodyne receiver is designed to efficiently detect and demodulate these signals.

Microcontroller Programming (e.g., Arduino)

1. Transmitter (WL102): Program your microcontroller to send digital data (e.g., ON/OFF pulses) to the DAT pin of the WL102. Libraries like "RCSwitch" or "VirtualWire" are commonly used for encoding and transmitting data.
2. Receiver (WL101): Program your microcontroller to read digital data from the DO(DATA) pin of the WL101. The same libraries (e.g., "RCSwitch", "VirtualWire") can be used to decode the received signals.
3. โปรโตคอลข้อมูล: Ensure that the data encoding and decoding protocols used by the transmitter and receiver microcontrollers are compatible.

การพิจารณาช่วง

The effective range of the modules depends on several factors, including antenna quality, power supply voltage (for transmitter), environmental interference, and line of sight. Optimal antenna tuning and clear line of sight will maximize range.

การซ่อมบำรุง

• ให้แห้ง: Protect the modules from moisture and humidity to prevent corrosion and damage.
• การเชื่อมต่อที่สะอาด: Ensure all pin connections are clean and secure.
• หลีกเลี่ยงความเครียดทางร่างกาย: Handle the modules carefully to prevent bending pins or damaging components.
• การดูแลเสาอากาศ: Ensure antennas are not bent or damaged, as this can significantly impact performance.

การแก้ไขปัญหา

• ไม่มีการรับสัญญาณ:
  • Verify power connections to both modules.
  • Check antenna connections and ensure they are properly sized for 433MHz.
  • Confirm that the transmitter and receiver are operating on the same frequency (433MHz).
  • Ensure the data encoding/decoding libraries and protocols are correctly implemented.
  • Reduce distance between modules and check for obstructions or sources of interference.
• ระยะสั้น:
  • Improve antenna quality (e.g., use a proper quarter-wavelength wire antenna).
  • Increase transmitter power supply voltage (within specified limits).
  • Minimize environmental interference (e.g., other 433MHz devices, Wi-Fi routers).
  • ตรวจสอบให้แน่ใจว่าตัวส่งและตัวรับอยู่ในแนวสายตาที่ชัดเจน
• การทำงานเป็นระยะ:
  • ตรวจสอบการเชื่อมต่อที่หลวมหรือรอยบัดกรีที่ไม่ดี
  • Ensure stable power supply to both modules.
  • Consider adding decoupling capacitors near power pins if experiencing noise issues.
• Module Appears Damaged:
  • Inspect for visible signs of corrosion or physical damage. If found, replacement may be necessary.
