• Highly accurate Temperature, Humidity and Barometric Pressure Sensors.
• Globally unique 64-Bit serial number.
• Updates temperature data every 2 seconds.
• Updates relative humidity, dew point, humidex, and heat index readings every second.
• Updates hPa/millibars and inches of mercury data every second.

• Updates light data readings 4 times per second.

• Supports Conditional Search command, with user-definable conditions.
• Uses 1-Wire communication protocol.
• Compatible with all EDS and Maxim 1-Wire bus masters.
• Pass-through connector for easy daisy-chaining of sensors.
• Latching Relay may be controlled independently or change due to alarm status.
• LED may be controlled independently or change due to alarm status.
• Applications include thermostatic controls, industrial systems, consumer products, thermometers, or any temperature/humidity/light/barometric pressure sensitive system.

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.
