Review on Gikfun Digital 38kHz IR Receiver Transmitter Sensor Module Kit for Arduino (Pack of 3 Sets) EK8477 by Renee Robinson

Revainrating 4 out of 5

Works great with 3.3V ESP8266

Both receiver and transmitter worked fine with my 3.3V ESP8266 NodeMCU board. in my case) contacts. Uses the IRRemoteESP8266 library. The transmitter isn't very wide (can't bounce off the ceiling like my remote), but the range is at least 5-10 feet. didn't try anymore.

Pros
  • Electronics
Cons
  • Ugly packaging
