Environment Monitors

Environment monitors provide real time data and information on the environment in which critical systems including IT servers, networking peripherals and Internet of things (IoT) devices are operating. The data can be logged for analysis and instant alarms generated when the recorded measurements rise above pre-set points with alarms issued via email, SMS and phone calls to stored email addresses and phone numbers. Data can also be collected via SNMP over an Ethernet network or pushed to a Cloud-based monitoring portal for access via a suitable HTTP/HTTPS internet browser or mobile phone application. Environment monitors help prevent damage to critical IT operations caused due to sudden temperature and humidity rises, water leaks, smoke and fire and can also help with server capacity planning and energy efficiency.

  • How to Monitor Server Room Temperature and Humidity Levels

    Climate change is driving up ambient temperatures and causing extreme weather patterns. For server room and datacentre operators, these environmental issues are placing a greater strain on their critical infrastructure systems. Server room air conditioning systems are placed under greater load during heatwave conditions and UPS systems must use their battery power more often to cover small power outages and complete mains power failures.

  • How to Install Server Room and Rack Level Monitoring Systems

    There are several good reasons for monitoring a server room or datacentre for temperature and humidity, but should you place sensors and detectors at the server rack or room level and just how many sensors is the right number?

  • How to Select A Server Room Monitoring System

    Rising cooling requirements are a common problem faced by many organisations as they adopt the latest server technologies, including high power computing. The higher the power draw of the latest servers the greater the need for air conditioning as their kW power draw adds an equal demand to the size of the air conditioning required. Edge Computing and micro data centres add another layer of complexity to the need for a dedicated remote environmental monitoring system.

Related FAQs

  • What is the ideal temperature for a server room?

    The most widely adopted temperature range for a server room is 18-25°C. This ambient temperature range provides a comfortable environment for technicians and engineers to work in, and a suitable environment in which to run IT servers, networking devices and associated critical infrastructure including uninterruptible power supplies. Below 18°C and the room can become a little too cool and energy is wasted cooling the space. Above the temperature and the server room becomes a little too warm with the potential for humidity related problems. Whilst this is an overall suitable server room temperature range, it is important to identify ‘hot-spots’ i.e. warmer temperatures within the room and server racks which could potentially lead to heat-related problems.

  • Do you provide an installation service?

    We provide a complete installation and commissioning service for the environment monitoring solutions we supply. Please contact us for a site specific quotation.

  • Can you supply multi-sensor environment monitors?
