Wireless Waterproof Digital Temperature Sensor

This is wireless, battery operated, waterproof temperature transmitter. The wireless temperature sensor is configured to transmit a temperature reading every 5 minutes. The device sleeps in between transmission in order to save battery power and is awoken every 5 minutes by an internal timer. This allows the device to be used for around 1 year on a single coin cell battery. The transmission interval can be configured between 1 minute and 999 minutes. If powered externally then the device can operate in a fully awake mode and temperature readings can be requested from the sensor in a request/reply fashion.

Technical Specs:

• Includes waterproof temperature sensor on 3 feet of wire. Wire and sensor are waterproof. The RF Module in the cream case is not waterproof. 
• 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
• Sensor 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 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.
