How to monitor data room temperature
Data room temperature monitoring can can involve more than just hanging a thermometer on the wall. Measurements should be taken from at least two locations
Isn’t as simple as a thermometer. There a little issue called airflow monitoring that needs to be in places as well. If you already own a BitSight or SensorProbe, you probably have a spare port.
Why not add another temperature sensor for across the room or an airflow sensor so that you have a more ambient environmental monitoring solution for very little money?

Ravica Sensor Probes help at the WaterPark
A few weeks ago, I wrote a blog about how I helped a local amusement park solve an overheating problem with Ravica’s sensor probes. Luckily, I schedule follow up calls to make sure that everything is working as planned. I found out that they have another issue that I can help with.
This amusement park has an attached water park with 20 plus rides. The water for all of these rides is supplied from three pumping stations. Each pumping station has a small data center. The pump section of each of these units has all the emergency equipment that you could ask for, but the data center lacked.
A few weeks ago, they had one of their sump pumps fail. The water backed up quite a bit and flooded the floor of the data closet. The good news is that they only had to replace a few of the items that were near the floor, but it was clear that they needed a solution.
I suggested that they get the BitSight2 and use the water sensors along with the AC voltage detector. The water sensor would detect if any water is getting near the door. It would then alert if the water starts to build up near the door. We then would use the AC Voltage Detector to monitor the power coming from the sump pump. Now we can detect if the pump kicks in and turns off. If water is getting to a certain point and the pump is not on, you need to check the situation.
The BitSight2 can store all this information for historical reporting. Now they can generate reports on how many times the sump pumps had to kick in and how many times the water level reached the marked point.
The customer placed the order today and we are going to implement the solution next month. I can’t wait to see it in action.

The future of airconditioning and how the rest of the world can monitor temperature
I just found an entry on Slashdot about a deal between IBM & Carrier to create and market a web enabled air conditioner. Apparently you are able to gain complete control of the unit via the simple web interface. Being a geek, this intrigued me. What about everyone else who cannot obtain one of these units?
Being able to log in and monitor the environment is something you can do with the Ravica line of SensorProbes. I would suggest getting one of the temperature and humidity probes to start with. From my research, high humidity plays a big role in the cost and operation of your air conditioning units. Being able to trend and be alerted during these times can be beneficial.
Next, I would use the airflow probe to tell me when the unit is on. I know, it is an odd way to detect the air conditioners state, but trust me, it’s logical. You can use an airflow sensor on any type of unit. Like the one in the above picture or built-in industrial type. With an airflow sensor, you are not limited to testing current flow or temperature.
Last, but not least, I would use the Sensor Controlled Relay to be able to turn off the unit, if you needed to, in an emergency situation.
So the good news is that you can implement Ravica’s environmental probes in various ways to help monitor your environment. What’s even better is that this technology is available to every one.

How to reduce false positives and frequent temperature alerts
Filed under: Data Center, SensorProbes, environmental monitoring, temperature monitoring
Previously, I wrote about managing the sensitivity of your motion detector to prevent or reduce false positives from normal environmental motion, while maintaining the security that the motion detector sensor provides. I thought I would elaborate on the subject by providing some tips on how to limit frequent alerts and false positives for any environmental monitoring sensor, like temperature.
As I mentioned before, the “continuous time to report,” or “rearm” as it is called on the SecurityProbe, are an excellent way to say, “Don’t alert me as soon as a sensor goes into a ‘warning’ or ‘critical’ status. However, if it has been in a ‘warning’ state for 30 seconds, let me know.”
Another way to limit how often – or how easily – your BitSight2 or SecurityProbe sends you Skype alerts or emails is to adjust the “reading offset” field, which can be found under each sensor’s advanced settings. The “reading offset” forces the sensor’s reading to move over or under a certainly value before generating an alarm. So basically, if your temperature upper “warning” threshold is set to 80 degrees and your “reading offset” is set to 2, and the current temperature is 79 degrees, then your SensorProbe will not alarm until the temperature drops another degree.
This prohibits the sensor from being right on the verge of a threshold and consistently bouncing between two statuses. You don’t want 20 emails in your inbox because the temperature in your data center is exactly on your threshold and wobbling back forth between “normal” and “warning.”
Another way of limiting alerts during off hours, maintenance windows or times when you are not really concerned with the readings breaching a threshold is to use the calendar feature. Please note that the calendar feature is available only on the SecurityProbe line of SensorProbes.
Block off times that you do not wish to receive alerts and the SecurityProbe will ignore the breached thresholds during those time frames. Perhaps you don’t want to receive alerts during the day, because people are always present and aware of the environmental conditions in the locations you are monitoring. However, maybe you want the temperature of your walk-in cooler monitored at night, when no one is in the building.
Whatever the reason, these are two great tips for better managing your alarms. This ensures that your alarms are more meaningful and so when you or you staff see an alert from your BitSight2 or SecurityProbe, you know it is time to act.

Universities, colleges and research labs need environmental monitoring
Often times there are various departments on a campus, which house and display wet/dry work areas. There are research labs, reference libraries, conference rooms, administrative offices, computer labs, etc. that ideally should stay within an optimum environmental range.
Our product’s primary function is to meet the teaching and research needs of the schools. Because the risk of inappropriate humidity and temperature levels exists, having those work areas monitored for items such as temperature, humidity, water, smoke, power outages, etc., reduces the risk of valuable work and/or equipment loss. Calamities caused by poor environmental conditions can negatively impact the education infrastructure, students and lectures.
To prevent these hazards, a small network of sensors monitoring various resources can help avoid catastrophes by alerting key staff members.

Mount Wilson Observatory In Danger From L.A. Fire
I just read this post on Slashdot:
“Mount Wilson is in danger from the Station fire burning near L.A. Their servers have gone offline, but there’s a temporary mirror cam. It doesn’t look good. Picture twenty-four on the L.A. Times photo gallery shows the observatory from the air. If anyone has any inside news on the condition of the facility, I’m sure there are lots of people on Slashdot that would love to hear it.”
It got me wondering about what type of SensorProbes they have. Most companies will never see this size of fire, but even a tiny fire can put a server room out of commission. That is why it is so important to use sensor probe technology to monitor our environment and alert us when something is wrong.
Anyway, I don’t want to use this as a sales pitch. So, let’s use the fire in California to remind us to check our home and office fire detection systems.
My prayers go out to all of the fire fighters, the people who have lost their homes and the people who’s homes are in danger.

The importance of monitoring airflow in the office
In a previous blog, Mike mentioned the importance of monitoring the airflow in your data center, but recently we were reminded of just how important airflow is in the work environment. Normally, our office is quite chilly. However, yesterday, the employees of Ravica were treated to nice a nice toasty office to work in. It was certainly a welcome change.
The reason for our cubicles being so nice and warm was because the air conditioning (which is normally blasting non-stop) was not turning on. After several hours, the nice toasty office become a stagnant bog of stale air. Breathing nothing but other people’s CO2 was getting my coworkers and I very sluggish and lethargic – not to mention hot and sweaty.
Luckily, we had a couple of airflow sensors placed in front of the air conditioning vents. As I mentioned, the air conditioning in our work area is typically blowing all day, and quite hard, so to have it shut off for a while and let the office temperature rise a bit, is actually a good thing. However, we can now see that if it does not start back up in a reasonable time frame, things can go too far in the other direction.
To alleviate the issue of getting email alerts from the airflow sensor every time the air conditioning unit shut off, we tweaked the “Continuous time to report” field, under that sensor’s setup screen. Now we can occasionally get a reprieve from our normally frigid conditions, but if the air conditioner stays off for more than a couple of hours, the building manager and our office manager get an email alert. Of course, since we have the airflow sensor connected to a SecurityProbe, we can use escalated notifications. So if for any reason the building manager does not acknowledge the alert within an hour, then he gets a text message sent directly to his phone.
So it is certainly important to keep your expensive data room equipment from overheating, but it is just as important to keep your employees from overheating as well.
