Can I test the equipment before buying?
Yes, selected devices are available for a free 30-day trial.
Do you offer volume discounts?
Yes, we prepare individual quotes for larger orders — use the quote form.
Environmental monitoring — temperature, humidity, water leaks, access
Air conditioning fails in your server room at 3 a.m. A water leak floods the warehouse over the weekend. A technical room door left open. You find out in the morning — or you get an SMS alert within 30 seconds. The difference is a EUR 170 sensor versus EUR 50,000 in damage. Our systems monitor 24/7 and raise the alarm before losses occur.
Remote control and automation over the Internet
Switch devices on remotely, restart servers, manage power — from anywhere. Inveo and Papouch relay modules with LAN/WiFi interfaces. Connect, configure once, control from your phone.
Power management
Smart PDU power strips with per-port energy metering. You know exactly what each device draws and can remotely switch off anything that doesn't need to run. A lower energy bill and full control over your infrastructure.
Running multiple sites? One EnviSensor + CE MonitorApp system monitors every location from a single dashboard.
802.3af (PoE) supplies 15.4 W at the switch port and guarantees 12.95 W at the device. An environmental logger needs a fraction of that, so any PoE port will do.
The sensor lives on the LAN like any other host: built-in web page, SNMP read, JSON or XML over HTTP. No driver, no software.
Check five things before buying: standard, alarm channel independent of the cloud, number of sensor inputs, probe length, and what happens when the switch loses power.
The UPS that feeds the switch also feeds the sensor. Put the PoE switch on the UPS, and the logger keeps reporting through the outage.
Use a buffered probe: a sensor in a glycol vial or aluminium block reads the temperature of the contents, not of the air that swings 5 °C every time the door opens.
Log at 30-minute intervals or shorter, with ±0.5 °C accuracy and a calibration certificate. Both the CDC and EU GDP expect this.
Set an alarm delay of 15–30 minutes on the warning threshold. Door openings then never wake anyone; a failed compressor still does within the hour.
Records must be exportable and retained: the auditor wants the chart for the week the freezer failed, not a signed sheet saying it was fine.
ASHRAE class A1 equipment is designed for an inlet of 18–27 °C recommended and 15–32 °C allowable. Measure at the inlet, not on the wall.
A closed rack in a closet without cooling can run 10–15 °C hotter at the top than at the floor. One sensor at the top front is the minimum that tells the truth.
The UPS battery is the first thing to die: VRLA batteries are rated at 20–25 °C and lose half their life for each 8 °C above that.
Power problems cause 45 % of serious outages and cooling 19 % (Uptime Institute 2025). In a small closet the two are the same failure.
