They are addressable and can be grouped into one of 255 zones, with each zone capable of individually addressing 255 devices, giving a total of over 65,000 unique addresses. SmartRFy modules are designed to be both easy and flexible to use by providing three levels of control: Zero configuration (out-of-the-box) © Hobby Components Ltd... - Page 6 For example, a SmartRFy relay module can be reconfigured to control a heating system based on the temperature transmitted from a remote sensor or, turn on a flood light for a set amount of time when triggered by a remote © Hobby Components Ltd...

This sample rate can be changed via the serial interface using the temperature (TTT) and humidity (HTT) transmit rate commands and can be set anywhere between 10 and 65535 seconds. Setting either transmit rate to 0 will disable reading and transmitting of that measurement. © Hobby Components Ltd... -
Page 12: Pir
Note: There is no pull-up resistor on the S input pin and so it will float between a logic high and low when disconnected from the sensor. Therefore it is recommended to connect this pin to 5V using the supplied jumper when a PIR sensor is not connected. © Hobby Components Ltd... -
Page 13: Ldr
It consists of an open-collector output with a 10K pullup resistor and is capable of sinking up to 100mA of current. © Hobby Components Ltd... -

The sensor module includes a set of 3 LEDs which indicate the current state of the module. PWR LED (green) Indicates the module is currently powered. TX LED (red) Indicates the module is currently transmitting. PIR LED (amber) Indicates a connected PIR sensor is currently triggered (S = high). © Hobby Components Ltd... -
Page 15: Serial Uart
Note that when receiving passive serial data from a remote SmartRFy device, the modules receive serial buffer is limited to 25 bytes and the maximum data transfer rate from a remote device is limited by the RF transfer rate and not the actual serial port connection speed. © Hobby Components Ltd... -
Page 16: Default Configuration Settings
Note: Connecting the module to a PC via its serial port will require an additional USB to serial adapter (see Hobby Components items HCARDU0011 or HCMODU0076). Clear (Factory Reset) The module is capable of storing a number of user configuration settings in its non-volatile memory. -
