WIFI-1WIRE

Monitor Temperature and Humidity Via Your Wi-Fi Network

Probe-style sensors on a 25’ leader cable allow you to leverage your existing Wi-Fi network to monitor environmental conditions in every corner – hidden or visible – of your facility.

The WIFI-1WIRE makes it easy to monitor conditions in a wide variety of spaces, including:

  • Refrigerators and freezers
  • Ovens and dryers
  • Warehouses
  • Heating and cooling ducts
  • Data cabinets

Integrates With Your Monitoring Systems

  • WIFI-1WIRE readings populate seamlessly into the WiNG-MGR’s user interface, which also provides an optional calculated dew point reading.
  • If you’re using a BMS, the WIFI-1WIRE transmits temperature and humidity information via a UDP packet to your BMS.

Wireless and Battery Powered

RLE’s Wi-Fi sensors are compact and unobtrusive, yet provide an industry leading battery life – WIFI-1WIRE sensor batteries will last up to FIVE years at room temperatures.

No wires are required for power; no wires are required for transmission.  The 1-wire sensor that attaches to the transmitter is on a 25′ leader cable, allowing you to monitor conditions in a closed environment, such as a refrigerator or freezer, while the transmitter portion of the device remains in a location that allows it to communicate with the WiNG-MGR or a BMS.

Designed With Security in Mind

  • Only allows one-way communications.
  • Supports WPA/WPA2‑PSK encryption.
  • Encrypted data storage for network and configuration information.

Key Features

  • Connects to a probe-style 1WIRE-TS or 1WIRE-THS sensor – sold separately
  • Transmits on your existing Wi‑Fi network
  • Supports DHCP or static IPv4 addresses and static IPv6 addresses
  • Configurable transmission rate
  • Optional calculated dew point when used with the WiNG‑MGR
  • Affordability and reliability that are second to none
