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