Wireless Waterproof Digital Temperature Sensor

Wireless Waterproof Digital Temperature Sensor

$24.95 Sale

This is a wireless, battery-operated, waterproof temperature transmitter. The wireless temperature sensor is configured to transmit a temperature reading every 5 minutes. The device sleeps between transmissions to conserve battery power and is awakened 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, the device can operate in a fully awake mode, and temperature readings can be requested from the sensor via request/reply.

Technical Specs:

  • Includes a waterproof temperature sensor on 3 feet of wire. The wire and sensor are waterproof. The RF Module in the cream case is not waterproof. 
  • The Digital Sensor is DS18B20 for high accuracy (+/- .5 °C) 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
  • Sensor based on the high-performance RF transceiver based on the market-leading CC1100 SOC.
  • A wide operating voltage range of 2-3.6V makes the devices well-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.
  • Driverless installation.
  • All the devices are highly configurable through the serial port or over the air using the LLAP messaging protocol specified in the manual. 
  • The base station communicates via a serial port (TTL UART).
  • Communicates in clear ASCII 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.
  • A virtually unlimited number of devices can be deployed—99,999 Personal Area Network IDs, 10 channels per frequency, and 7,744 Device IDs per network.
  • Super-low power consumption allows devices to run on a coin cell battery for extended periods (up to 1 year, depending on transmission rates).
  • Supports six 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 microcontrollers like Raspberry Pi and Arduino: Tx, Rx, GND, 3V3.
  • A battery monitor to keep track of power consumption.
