* This sketch receives and decodes data from a 433MHz thermo/hygro weather sensor.
|
|
* The received data (temperature, humidity, channel) is echo
|
|
*
|
|
* Setup:
|
|
* - Connect digital output of a 433MHz receiver to digital pin 2 of Arduino
|
|
* - Enable the serial monitor at 115200 baud.
|
|
