The Sensor is DS18B20 for high accuracy and repeatability.
The DS18B20 temperature sensor is used to detect the temperature. It 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
DS18B20 is connected to sensor via 1 or 2 meter water proof cable.
All devices are based on the high-performance RF transceiver based on the market-leading CC1100 SOC.
The 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.
All the devices are highly configurable through the serial port or over the air using the LLAP messaging protocol specified in the manual.
Communicates in ASCII clear text, making it very easy to exchange data between devices over the air.
A virtually unlimited number of devices can be deployed. 99,999 Personal Area Network ID’s, 10 channels per frequency and 4,000 RF2 and 15M RF4 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).
