The EDS 1-Wire Temperature & Light Sensor, OW-ENV-TL, offers an innovative way to easily monitor and control temperature and light in indoor environments. The wall mount sensor features a high accuracy temperature sensor; as well as 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 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 Temperature / Light Sensor's alarm functions can operate independently of the 1-Wire host adapter the sensor can be used as a standalone Thermostat.
