The EDS Environmental Sensor Line, OW-ENV, offers an innovative way to easily monitor and control temperature, humidity, barometric pressure, and/or light in indoor environments. The wall mount sensor features high accuracy temperature, humidity, and barometric pressure sensors; in addition to a light sensor, an LED, conditional search support, and a pass-through 1-Wire connection. Together these features offer an efficient and flexible system for monitoring the temperature, humidity, barometric pressure, and light levels at one or more locations within a building.
The sensor was specifically designed for easy communications. Any general purpose 1-Wire host adapter* should be capable of reading data from the sensor.
The conditional search support allows the 1-Wire host adapter to quickly identify the alarm status for numerous parameters; and the LED and optional latching relay can be configured to behave in a variety of ways, including:
- Activate when an alarm parameter is met and deactivate when the alarm byte is cleared.
- Activate when an alarm parameter is met and deactivate when readings return to normal range.
- Controlled independent of alarm status.
The LED and optional relay response times are extremely fast; the sensors are able to respond appropriately (activate fan/alarm siren/etc) even before the monitoring application is aware an alarm has been triggered. Since, the EDS Environmental Sensor line's alarm functions can operate independently of the 1-Wire host adapter the sensor may be used as a standalone Thermostat, Humidistat and/or Pressurestat.
