Temperature Sensor
The temperature sensor detects ambient temperature. It can be configured to send out alerts when the temperature goes beyond a predefined temperature range. The alerts are sent out via the alert profiles.
The temperature sensor is connected to Varius Message Router via a USB cable. The length of the cable can be up to 5 meters, allowing greater flexibility in the choice of location to place the temperature sensor
Setup
- Connect the temperature sensor to one of the USB port of the VMR.
- Access the Sensors Configuration page to configure the sensor.
Configuration
You can access the Sensors Configuration page by
- Clicking on the wrench on the Control Panel page.
- Access the Sensors Configuration menu item in the Sensors menu.
Remember to save the settings and stop and start the Sensors service at the Control Panel page for each configuration change.
Basic configuration
To activate the sensor, check the “Active” checkbox.
You can change the name of the sensor in the “Name” field and its temperature display to be in Celsius or Fahrenheit in the “Monitors” field.
If you need to calibrate the sensor, check the “Calibrate” checkbox and key in the value to add or subtract from the sensor reading.
Trip Conditions
You can configure the sensor to trip when the following conditions occur:
- Temperature is lower than a preset temperature for longer than a predefined period.
- Temperature is higher than a preset temperature for longer than a predefined period.
The “Low” section allows you to set the sensor to trip when the temperature falls below a preset temperature:
- Check the checkbox to activate this feature.
- Key in the temperature value.
The “High” section allows you to set the sensor to trip when the temperature goes above a preset temperature:
- Check the checkbox to activate this feature.
- Key in the temperature value.
The “Trip mins” field specifies the number of minutes that the temperature must be below or above the preset temperature before it is considered tripped.
The “Recovery mins” field specifies the number of minutes that the temperature must be in the normal range before it is considered recovered.
Example:
Setting:
- Low: 20 Degrees Celsius
- High: 25 Degrees Celsius
- Trip mins: 5
- Recovery mins:5
Sensor will trip if
- the temperature goes below 20 Degrees Celsius (Low) for 5 minutes (trip mins).
- the temperature goes above 25 Degrees Celsius (High) for 5 minutes (trip mins)
- the temperature goes to between 20 Degrees Celsius and 25 Degrees Celsius for 5 minutes (recovery mins).
Alert Conditions
The temperature sensor can be configured to send out alerts for the following conditions:
- Sensor is tripped.
- Repeat alert interval is reached when sensor remains tripped.
- Sensor has recovered.
The fields in the “Alert conditions” section have the following functions:
- Trip checkbox: Send alert when sensor is tripped
- Repeat checkbox: Send repeat alerts when sensor.
- Repeat mins field: The repeat alerts will be sent at an interval of the number of minutes set.
- Recovery checkbox: Send alert when the sensor has recovered.
The “Alert mechanisms” section contains the configured alert profiles.
The fields in the “Alert mechanisms” section have the following functions:
- Email section: Check the respective checkbox to send out the alerts using the email alert profiles.
- SNMP section: Check the respective checkbox to send out the alerts using the SNMP alert profiles.
