  • It's Hot! It's Cold! Oh No... It's Your Fluctuating Server Room Temperature Again...

    We know that every room, especially a server room, has its own microclimate. Even sensors that are inches apart can read different values! Although similar applications might share the same temperature threshold range, every sensor placement location is unique. It sounds strange; that there would be such fluctuations in temperature within inches, but this happens because your server room has its own minature weather pattern!

    So how do you figure out the correct temperature range for monitoring your server room? Or where to place your sensor? As many conditions as there are for the actual ourdoor weather patterns, there are many variables for sensor placement and operational range because of the changing indoor microclimate.

    Essentially, in order to determine the right thresholds for your server room "environment", you need to acquire adequate baseline knowledge. This process is called "baselining", which involves monitoring your server room first to establish a history of normal conditions. Temperature is a significant threat to your equipment and in order to battle this, you need to discover and establish your server room's microclimate (i.e. baselining)!

    Baselining is basically achieved through studying the space of your server room while considering the components within it. Thic can be done to determine the proper ranges for both temperature and humiditySo what spots are the most critical for consideration when it comes to sensor placement?

    1. Hot Spots
    At the bare minimum, place at least one sensor in a central location in the room. Note: every room has its own mini weather pattern, and conditions from one part to another can vary based on what the room contains and where vents/returns are located. The simplest rule of thumb is that heat rises. So, the higher the sensor placement, the warmer the temperature

    2. Cooling Vent Locations
    Whether it is an air conditioner, economized cooler, or another chilling device, it will affect the sensor reading depending on proximity of the sensor to the vent. If you want to monitor whether your cooling unit may be going out at different times,place a sensor in the air duct and you can determine when the cooling unit is off. Placement of a sensor in close proximity to the cooling unit may cause the sensor to pick up cooling unit "cycles", sending you false alerts in the process.

    3. Exhausts
    Besides cooling vents, you need to also consider hot vents from server cabinets or compressors. Placing a sensor near or in between these areas is crucial as high temperatures can cause damage to hardware. The exhaust-based alerts will draw attention to the high temperatures within the servers, allowing you to prevent loss of hardware (and revenue!)

    4. Ancillary Humidification Systems
    These systems help control humidity. Too much humidity can cause condensation, which leads to electrical shorts. Not enough humidity causes one to have quite the mini-electrifying experience with static electricity at its peak. Place your humidity sensor in a location seperate from the ancillary humidification system in order to prevent the sensor from getting shorted and to avoid false humidity readings.

    By monitoring temperature and humidity, one can have early warning of any disasters looming in your server room. It is always better to prevent a disaster rather than mop up after it (speaking of, flood sensors are great too!).

    Happy Monitoring!

  • The Endless Possibilities with the Release of Dry Contact Smart Sensor

    Temperature@lert has recently developed a dry contact smart sensor. We had previously developed adapter boards for industrial agricultural sensors, such as soil moisture and wind speed. Expanding beyond the agricultural industry, our latest adapter board can integrate into most monitoring and alarm systems that have the capability for dry contact concatenation.

    Through expansion and integration, the Temperature@lert Cellular Edition will be able to alert users to fire alarm panel signals, air conditioning unit state changes, doors/windows opening and closing, etc. Dry contact is essentially a switch where it has two basic outputs that are relevant to individual applications. Dry contact will produce an output of either: “open” or “close”, “on” or “off”, “is” or “isn’t” to name a few. For example in commercial refrigeration, an user can be alerted if a refrigerator door has been “opened” and have the alert triggered to notify when the door has been “closed”.

    “These outputs can translate into numerous possibilities for Temperature@lert’s latest smart sensor,” notes CEO and President, Harry Schechter. Temperature@lert Cellular Edition Users will be able to connect their devices to their current alarm systems where dry contact is available. Schechter also notes that, “users will not only be able to be alerted to temperature, humidity, and floods but in addition they can monitor doors, windows, lights, and power for generators among others”. The potential for integration with numerous systems and Temperature@lert Cellular Edition’s ease of usability puts Temperature@lert at the forefront of innovation in monitoring beyond the basic monitoring offerings for IT server rooms, commercial refrigeration, biopharmaceutical and medical supplies, energy management, and property management.
