Profile: Esensors, Inc. specializes in designing & producing networked sensors, sensor data acquisition, and toxic gas monitors. Our EM01B websensor is an environmental monitoring sensor that provides accurate measurement of temperature, relative humidity and light. This sensor continuously measures temperature and relative humidity of room air. It connects with the network to provide real time data logging and historical trending. If the temperature or humidity goes beyond a preset threshold, an alert can be sent to any number of recipients through e-mail, cell phone, or pager. The environmental monitoring unit (EMU) is used as an early-warning system to detect hostile or hazardous gas levels. Alarms will be activated when the level of certain gas exceeds the preset thresholds. Users can monitor the detection levels over the web anytime, anywhere. The EMU is web-enabled and IP addressable in addition to having wireless communications capabilities.
