RemoteSensor library for Arduino.
Made by Randy Simons.

This library provides an easy class for Arduino, to send and receive signals
used by some common weather stations using remote 433MHz sensors, like those
made by Cresta.

Cresta is just a brandname. The original OEM seems to be Hideki Electronics.
There are other brands which use the same hardware and / or protocol. As far
as I know these include Mebus, Irox, Honeywell, Cresta and RST.

This software is based on the work of Oopsje. See docs/CrestaProtocol.pdf

See SensorTransmitter.h and SensorReciver.h for details!

Installation of library:
 - Make sure Arduino is closed
 - Copy the directory RemoteSensor to the Arduino library directory (usually
   <Sketchbook directory>/libraries/)
   See http://arduino.cc/en/Guide/Libraries for detailed instructions.
 
Default installation sender & demo:
 - Connect tha data-in-pin of a 433MHz transmitter to digital pin 11. See 
   docs/hardware setup.jpg.
   (Note: your hardware may have a different pin configuration!)
 - Start Arduino, and open the example: File -> Examples -> RemoteSensor ->
   ThermoHygroTransmitter
 - Alter addresses/devices to reflect your own setup. Otherwise nothing will
   happen.
 - Compile, upload and run!

Default installation receiver & demo:
 - Connect the data-out-pin of a 433MHz receiver to digital pin 2. See photo.
  (Note: your hardware may have a different pin configuration!)
 - Start Arduino, and open the example: File -> Examples -> RemoteSensor ->
   ThermoHygroReceiver
 - Compile, upload and run
 - Open serial monitor in Arduino (115200 baud)
 - Wait for your 433MHz-sensor to transmit (less than 1 minute), and watch the
   serial monitor


Changelog:
RemoteSensor library v1.0.3 (20240204) for Arduino
 - Fix SensorTransmitter::sendPackage
 - Add ThermoHygroTransmitter::sendRainlevel

RemoteSensor library v1.0.2 (20130601) for Arduino 1.0
 - Reduced memory usage (Flash, RAM). Because of this, a small backwards
   incompatibility is introduced: The last parameter of
   SensorReceiver::decodeThermoHygro now is a byte instead of short.
 - Dropped support for Arduino pre-1.0

RemoteSensor library v1.0.1 (20120213) for Arduino 0022/1.0
 - Ignore obviously too short or too long signals in SensorReceiver, for better
   recognition rate.
 - Support for Arduino 1.0.

RemoteSensor library v1.0.0 (20110919) for Arduino 0022
 - Initial version
