WiSense IoT Dashboard
The WiSense IoT dashboard offers real-time sensor data collection and visualization on the cloud. The dashboard has a powerful relational database storage with fast response time for UI data updates. The UI comes with various visualization options and also supports configurable SMS/Email alarm generation features.
WiSense builds and maintains this dashboard for our customers. Our customers can use it even when they are not using WiSense hardware.
The dashboard can run in the cloud or locally within customer premises.
The snapshots below show a simple dashboard built for a customer’s factory having five WiSense WXI-RH/T-10 wireless sensor nodes sending relative humidity and temperature data to the cloud.
The customer has a (WiSense provided) login id and password to access this data.
The snapshot below shows the visualization screen which can show both real time and historic data. This particular snapshot is showing temperature (T) and relative humidity (RH) data stream from a WiSense WXI-RH/T-10 wireless sensor node installed in chamber 01.
The snapshot below shows the last received sensor data and associated time stamp from the sensor node in chamber-01. In addition, this screen allows the generation of e-mail/SMS alerts through configuration of sensor data thresholds for each sensor data stream.
I will take the relative humidity (RH) data to illustrate the threshold settings. The snapshot shows the upper threshold set to 80 %, the lower threshold set to 40 % and a hysteresis value of 2.5 %. The corresponding chamber will enter an alarm condition when –
- RH rises above 80 %
- Here the chamber enters the alarm condition “RH above upper threshold”
- RH falls below 40 %
- Here the chamber enters the alarm condition “RH below lower threshold”
The chamber is not in any alarm condition as long as the RH value is between 40 % and 80 %.
The hysteresis value of 2.5 % prevents unnecessary alerts (e-mail/SMS) from being generated in case the RH value fluctuates around the threshold value. It is up to the customer to choose the appropriate threshold and associated hysteresis value.
The dashboard will send out a e-mail and/or SMS to configured recipients if alert generation is enabled (“yes”) for the corresponding sensor data (see snapshot above) stream. An alert e-mail and/or SMS is sent when an alarm condition is entered as well as when the alarm condition gets cleared.
If customer has not enabled alert generation (“no”) for a particular sensor data stream, no e-mail/SMS will be sent out but this event will be recorded and displayed in the “alarms” history window shown in the snapshot below.
Once an alert (e-mail and/or SMS) is sent out, another alert will not be sent out until the alarm condition gets automatically cleared or a different type of alarm condition is entered. For example, if the RH value increases beyond 80%, the chamber will remain in this alarm condition until the RH drops below (80 – 2.5) = 77.5 %. Similarly, if the RH falls below 40 %, the chamber will remain in this alarm condition until the RH rises above (40 + 2.5) = 42.5 %.
