Product Description:

Low temperature wireless sensors use an RTD probe to accurately measure temperatures from -200 ° C to + 162 ° C. Perfect for critical low temperature applications such as freezers and coolers. User customization allows you to set the frequency of sensor readings and create notifications from the system when certain criteria are met or exceeded.

The low temperature sensor is not designed for humid, humid and very humid environments. This sensor should only be used in dry and low humidity environments. If you need a temperature sensor that operates at extreme temperatures and can resist humidity or condensation, please consider our thermocouple sensors.

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 have 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.

Built-in data storage allows sensors to store data if communication with a wireless gateway is interrupted (power outage, Internet connection cut 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 reestablished, 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.

The industrial sensors are delivered in an IP65, NEMA 4X, CE certified, waterproof and weatherproof enclosure. They are powered by a single 3,6 V industrial quality, replaceable battery (included).

An optional version powered by solar energy is also available. The solar powered version includes a rechargeable Lithium Iron Phosphate battery combined with a solar cell to keep the battery charged and at its optimal capacity. If there is no light at the level of the solar cell, the battery alone can continue to supply the sensor for 8 to 10 years.
