SensGuard DS18B20 wireless temperature sensor with probe for temperature ranges of –30°C to +120°C. Accuracy ±0.5℃. Resolution 0.1℃.


Remote temperature sensor with probe SensGuard DS18B20 is a wireless sensor for temperature monitoring in a range of -30°C and up to +120°C. This temperature sensor is powered by standard AAA batteries for up to 5 years. The sensor measures temperature within ±0.5℃ high accuracy and 0.1℃ resolution.

It has a 1.5m long temperature probe that can be installed in hardly accessible places. Temperature readings are delivered to an online database every 5 minutes through LAN/Internet gateways. DS18B20 Wireless temperature sensor can connect the data gateway within a range of up to 150m.



The LAN/Internet data gateway reads temperature metrics from up to 250 temperature sensors in the 150m range and forwards it to the online reporting portal SensWeb. You can check temperature statistics per each sensor or a sensor group, as well as full history about events and violations.

There is an option to set-up min/max temperature settings for every remote temperature sensor, as well as allowed violence time. This feature permits creating a flexible monitoring environment and the user will get the critical alarms only, avoiding spamming him by not essential and short-term events.


  1. Wireless temperature monitoring – in freezing and cooling equipment to detect failures and prevent food spoilage in supermarkets.
  2. Commercial properties and warehouses – remote temperature monitoring to avoid frozen pipes and frozen fire suppression systems.
  3. Food storage warehouses – centralized temperature monitoring.
  4. Wireless temperature transmitter – for heating and ventilation systems remote temperature monitoring.
  5. Temperature system monitoring – for art galleries or museums.
  6. Wireless temperature sensor – for greenhouse remote temperature monitoring.
  7. Data center and server room – temperature monitoring.




Temperature sensor with probe advantages

  • Wireless setup – installation of battery-powered temperature sensor takes some seconds only.
  • Notifications – a user will get a notification about the violence of specific min/max temperature range controlled by the sensor.
  • Accurate measurement – a digital thermometer for remote temperature monitoring with accuracy ±0.5℃ and resolution 0.1℃.
  • Long battery life – remote temperature sensor works using two AAA batteries for 5+ years.
  • Temperature probe – 1.5m long temperature probe allows measuring temperature in hardly accessible spots.
