Technical Specs:

  • 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.
  • The Digital Sensor is DS18B20 for high accuracy (+/- .5C) 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
  • The Analog Sensor is the NEC thermistor NTCLE100E3103JB0, ~1°C accuracy.
  • 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 a 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 used with a coin cell battery 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.
  • Battery monitor to keep track of power consumption.
