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_Water_RX

Receiver example for the above leak/flood sensor, 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_RX_Simple

A simple receive example, outputing received data on the serial monitor.

TinyTX_NanodeRF_emoncms

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

TinyTX_MAX1284_emoncms

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

TinyTX_NanodeRF_Cosm

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