HX1838 VS1838 NEC Infrared IR Wireless Remote Control Sensor Module For Arduino. The sensor uses HX1838, with high sensitivity and Operating voltage 5V. Output form Digital output. VCC: 3.3V-5V external voltage (can be directly connected to the 5v microcontroller and 3.3v microcontroller).
 
Kit theory test distance of about 5-8 meters, but the practical application depends on the ambient factors you use, as well as the middle barrier (such as diaphragm, glass, obstructions or other material blocking),
Receiving head with HX1838 with power work instructions lights, receive 38K frequency any remote coding data.
