Details

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 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 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.
