ການເຊື່ອມຕໍ່ເສົາອາກາດ
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.
ການສະຫນອງພະລັງງານ
- 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.
ການເຊື່ອມຕໍ່ຂໍ້ມູນ
- 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.
ຄໍາແນະນໍາການດໍາເນີນງານ
ຫຼັກການພື້ນຖານການດໍາເນີນງານ
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)
- 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.
- 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.
- ອະນຸສັນຍາຂໍ້ມູນ: Ensure that the data encoding and decoding protocols used by the transmitter and receiver microcontrollers are compatible.
ໄລຍະພິຈາລະນາ
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.
