Product Description:

The wireless water temperature sensor uses a 900mm waterproof probe to measure the temperature in water or non-combustible liquids. Perfect for monitoring temperatures in water storage tanks, swimming pools, aquariums and natural environments. User personalization allows you to set the reading frequency and conditions for e-mail or sms notifications.

Main “Internet of Things” solutions for companies

The sensors offer a range of standard sensors with a range of up to over 350m through walls (12 to 14 walls generally). The use of frequency spread spectrum (FHSS) also allows the sensors to benefit from better immunity to interference from other wireless devices.

Superior power management provides the sensors with almost twice the battery life of standard wireless sensors.

  • Button cell sensors typically last over 3 years.
  • AA and industrial sensors generally last up to 12 years.
The products use the new Encrypt-RF® Security system (256-bit Diffie Hellman key exchange and AES-128 CBC encryption for all sensor data messages). Security is therefore maintained at all communication points, gateway sensor, software gateway.

The integrated data storage allows the sensors to store the data if the communication with a wireless gateway is interrupted (power outage, Internet connection outage or out of range). Messages that cannot be delivered will be time stamped and stored in memory (up to the last 512 messages) until communication with the gateway is restored, in which case all messages will be transmitted.

Over-the-air updates allow products to be updated remotely if new patches or new features are available.
