SX1278 LoRa Module 433M 10KM Ra-02 Ai-Thinker Wireless Spread Spectrum Transmission Socket (lora module)

Description

Ra-02 is a wireless transmission module based on SEMTECH's SX1278 wireless transceiver. It adopts advanced LoRa spread spectrum technology, with a communication distance of 10,000 meters. It has strong ability of anti-jamming and has the function of air wake-up Consumption. Can be covering thousands of people in the district environment, particularly suitable for meter reading, smart home, burglar alarm equipment.

The LoRa series module Ra-01 is designed and developed by AI-THINKER Technology. The SX1278 RF module is mainly used for long-range spread spectrum communication. It can resist Minimize current consumption. Thanks to SEMTECH's patented LoRa ™ modulation technology, the SX1278 has a high sensitivity of -148 dBm with a power output of 20 dBm, a long transmission distance and high reliability. At the same time, compared with the traditional modulation technology, LoRa ™ modulation technology has obvious advantages in anti-blocking and selection, which solves the problem that the traditional design scheme can not consider the distance, interference and power consumption at the same time.

DC Voltage detection Sensor (DC Volt sensor)
Description

This module is based on a resistive divider principle design, make the interface terminal input voltage reduced 5 times, Arduino analog input voltage up to 5V, then the input voltage of the voltage detection module can not be greater than 5V × 5 = 25V (if used 3.3V system, the input voltage can not exceed 3.3Vx5 = 16.5V). Because Arduino AVR chips used in 10 AD, so the resolution of the analog module is 0.00489V (5V / 1023), so the voltage detection module detects a minimum input voltage of 0.00489V × 5 = 0.02445V.

Parameters:
  • Voltage input range: DC0-25V
  • Voltage detection range: DC0.02445V-25V
  • Voltage analog resolution: 0.00489V

Wiring the DC input connector:
   
  • the positive terminal connected to VCC,
  • the negative  connected to GND
  • Output interface:
  • " " is 5 / 3.3V,
  • "-" then GND,
  • "s" Arduino connected to the AD pin
