Technical Specs:

• Battery monitor to keep track of power consumption. 
  
• AA Housing with On/Off Switch
• Temperature Sensor is DS18B20 for high accuracy and repeatability.
• DS18B20 temperature sensor is used to detect the temperature Measures temperatures from -55°C to +125°C. Fahrenheit equivalent is -67°F to +257°F, ±0.5°C accuracy from -10°C to +85°C
• All devices are based on the high-performance RF transceiver based on the market-leading CC1100 SOC.
• Wide operating voltage range of 2-3.6V makes the devices suited for battery power.
• Current consumption: RX: 16.2 mA , TX: 15.2 mA. Deep Sleep : 0.005Ma (0.5 µA).
• Up to 1KM line of sight. Short range (30M) penetration of walls and floors.
• 128-bit AES encryption security.
• Driver-less installation.
• All the devices are highly configurable through the serial port or over the air using the LLAP messaging protocol specified in the manual. 
• Base station communicates through serial port (TTL UART).
• Communicates in ASCII clear text making it very easy to exchange data between devices over the air.
• Supports point to point, point to multi-point, multi-point to point and multi-point to multi-point.
• Virtually unlimited amount of devices can be deployed. 99,999 Personal Area Network ID’s, 10 channels per frequency and 7,744 Device ID’s per network.
• Super low power consumption allows devices to be use for long periods of time (up to 1 year depending on transmission rates).
• Supports 6 frequencies (433 MHZ, 915 MHZ (default US & Canada), 868.3 MHZ (default Europe), 868 MHZ, 903 MHZ, 315 MHZ)
• 10 channels per frequency.
• 4 pins for communicating with external micro-controllers like Raspberry Pi and Arduino : Tx, Rx, GND, 3V3.
