This is 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.

This is new ultra-thin 38K universal infrared IR Remote Control , NEC encoding format 1-21-key remote control, USB port stereo, car MP3, foot bath, lighting, digital photo frame, microcontroller development board, learning board, etc.

Note: IR Remote does not come with Battery (CR2025) you have to buy it separately.

    perfectly working! One must purchase it


  2. ykprakash (verified owner)

    Both the units purchased were tested and found working. You need to have a CR2032 battery, as it’s not supplied with the package. Be careful while removing the battery holder of the remote.
