Remotely Check Temperature/Humidity Levels & Receive Auto-Alerts

Use your smartphone, tablet, or PC to remotely monitor temperature and humidity levels in your home or business with the La Crosse Alerts Temperature & Humidity Monitor & Alert Kit. This kit includes one wireless temperature/humidity sensor (similar to a digital thermometer) and a wireless Internet Gateway. The sensor's built-in screen displays the ambient temperature and humidity, and sends data through the Gateway to your online account. It's perfect for preventing frozen pipes, food spoilage, and more.

  • Wireless temp./humidity sensor transmits data to Internet Gateway
  • Internet Gateway transmits data to your online account
  • View current readings at sensor display or online
  • Set Min/Max temp. or humidity levels to receive email or text alerts
  • Expandable system supports up to five main sensors total

How It Works

The Internet Gateway connects to your Internet router via Ethernet. The battery-powered indoor/outdoor temperature sensor can be placed up to 200 feet away from the Gateway, either mounted on a wall (hardware included) or simply placed on a tabletop.

Once the kit is setup, the sensor will take temperature/humidity readings every six seconds and send them wirelessly to the Internet Gateway, where it uploads measurements to lacrossealertsmobile.com for remote monitoring and alerts.

Monitor Min/Max Levels

In addition to remote monitoring, the La Crosse Alerts Temperature & Humidity Monitor allows you to receive automatic text or email notifications when temperature or humidity levels exceed your minimum or maximum setpoints. Notifications will also be sent if the main sensor loses its connection to the Gateway for more than one hour, or if it has low battery.

Expand the System to Monitor Multiple Areas

The Internet Gateway supports up to four additional temperature/humidity sensors (five total, others sold separately), allowing you to monitor additional areas. Add-on sensors are available in five different models: 1) original 2) with dry probe 3) with water probe 4) with wet probe, non-threaded 5) with wet probe, threaded.

Sensors with probes are composed of the main sensor with a small, secondary sensor probe attached by a 6-foot cable. Probes offer more versatile and targeted monitoring options for various applications.

Optional Sensor Probes

  • Wet: Monitors temperature/humidity of water, air or wet soil. Ideal for pools, spas, aquariums, ponds, gardens.
