Code for TinyTX nodes

##TinyTX_DS18B20 With DS18B20 temperature sensor.

##TinyTX_DHT22 With DHT22 temperature & humidity sensor.

##TinyTX_TMP36 With TMP36 Analogue Temperature Sensor.

##TinyTX_LDR_Meter
With LDR to read LED pulses on electricity meter.

##TinyTX_LDR With LDR to read light levels.

##TinyTX_ReedSwitch Detect a normally closed reed switch opening and closing with pin change interrupt to wake from sleep.

##TinyTX_Hall_Effect_Gas Using an A3214EUA-T or A3213EUA-T Hall Effect Sensor to read the pulse magnet on a gas meter.

##TinyTX_Rain_Gauge Using a tipping bucket rain gauge with a reed switch to indicate each tip. A pin change interrupt is used to wake the TinyTX

##TinyTX_Water A leak/flood sensor using the TinyTX, a 100K resistor and two wire probes. See below for a receiver.

##TinyTX_SRF_DS18B20 Version using the Ciseco SRF radio (http://shop.ciseco.co.uk/srf-wireless-rf-radio-surface-mount/) instead of the RFM12B Uses the SoftEasyTransfer library to send checksummed typedef structs (https://github.com/madsci1016/Arduino-EasyTransfer/) This is transmit only for now as receive requires a hardware modification to the TinyTX.

##TinyTX_OOK_DS18B20 Version using a cheap OOK/ASK radio and Manchester encoding. This is transmit only as these cheap radios are only transmitters.

Code for receiving end

##OSWIN ATMega1284P Emoncms gateway code For the code I am currently using on my gateway node see the separate repository here: https://github.com/nathanchantrell/oswin This support the RFM12B, SRF and OOK nodes. More info on OSWIN here: http://nathan.chantrell.net/oswin/

##TinyTX_RX_Simple A simple receive example for RFM12B nodes, outputing received data on the serial monitor.

##TinyTX_NanodeRF_emoncms For the Nanode RF (http://www.nanode.eu/) to upload multiple RFM12B nodes to emoncms

##TinyTX_NanodeRF_Cosm Nanode RF example to upload data from a single RFM12B TinyTX to http://cosm.com

##TinyTX_MAX1284_emoncms For the MAX1284 internet gateway (http://max1284.homelabs.org.uk/) to upload multiple RFM12B nodes to emoncms

##TinyTX_Water_RX Receiver example for the leak/flood sensor above, can be run on a Tiny TX and brings D9 high on a water alarm and D10 high on a low battery alarm. Could be used to trigger an external device, sound a buzzer etc. Same code could also be used on a Nanode/WiNode etc.

##TinyTX_SRF_RX_Simple Simple receive example for the SRF version.

##TinyTX_OOK_RX_Simple Simple receive example for the OOK version.
