  • E-1W - Low-Cost Environment Monitoring System

The ENVIROMUX® Environment Monitoring System (EMS) with 1-Wire Sensor Interface monitors critical environmental conditions, such as temperature, humidity, liquid water presence, power, intrusion, and smoke. When a sensor goes out of range of a configurable threshold, the system will notify you via email, web page, network management (SNMP), and/or SMS messages (via email-to-SMS).


The IoT system supports 24 single reading 1-wire sensors in any combination – temperature, humidity, dew point, or digital inputs – and 2 separate digital inputs. It functions independently or as an IP-connected remote sensor for the E-2D/5D/16D.

    How to connect Remote 1-Wire Temperature/Humidity Sensors over IP to the E-2D/5D/16D

    The E-1W(P) Remote 1-Wire Temperature/Humidity Sensors over IP can function as an IP-connected remote sensor for the E-2D/5D/16D. To add a remote IP sensor, access the E-xD web interface and select Monitoring > IP Sensors. Click on the "Add New IP Sensor" link on the bottom and key in the description and IP address of the E-1W(P). Next, select Sensor Type > E1W, then press the add button to connect it to the main ENVIROMUX unit. Up to four remote 1-wire IP sensors can be connected. All sensors connected to the E-xD, including the Remote 1-Wire Temperature/Humidity Sensors over IP, can be viewed on one summary page.

Testimonials

  • "We have 3 of the 4 buildings online and all is working great. Hope to get Building 4 completed tomorrow before the ultra-cold temps hit us. Overnight, we received lots of alerts from our second building as temperatures dropped below 45 … 44 … 43 … and by this morning down to 36 degrees. Low and behold, the installer left the outer door ajar while we were testing yesterday. Got a real world test overnight! The E-1W works as expected!"
