RJ45 interface adapter is a module to turn the DuPont cable interface into network cable interface (RJ45 connector). When using arduino to measure temperature and humidity, detect soil moisture and ambient light, the test location is often far away (over 2 meters) from the arduino board. In view of the general line of DuPont severe signal attenuation, you can use two RJ45 interface adapter module and a 5 m or 30 m of network cable to connect the sensor or other modules.
Note: This module is generally used in pairs.
