รหัสสินค้า LoRa-MODEM
ส่งผ่านได้ไกลและทะลุทะลวงกว่าความถี่สูง 2.4Ghz ทนทานต่อสัญญาณรบกวน และใช้พลังงานที่ต่ำ
ผู้ใช้งานสามารถส่งข้อมูล Protocol ต่างๆ เช่น Modbus RTU/ASCII ขี่ไปบนคลื่น RF
แทนการลากสาย
โดยข้อมูลที่รับและส่งแต่ละครั้งสูงสุดไม่เกิน 240 byte (payload)
การใช้งานต้องใช้ขั้นต่ำ
2ตัว
โดยต่ออยู่กับอุปกรณ์ที่ทำหน้าที่เป็น Master และ Slave ทุกตัว
รายละเอียด
LoRa RF Modem 920-925 MHz
Chip SEMTECH SX1276 (ไม่ใช้ Lora WAN Protocol)
ใช้เทคนิค Spread Spectrum Modulation และ Forward Error Correction
คู่มือ
คู่มือการใช้งาน LoRa Modem
การตั้งค่าด้วย Dip Switch
