key sensor features
SNMP & Modbus TCP sensor designed for monitoring temperature inside racks.

no pc required for the ServersCheck to operate once configured - measures temperatures -55C to +125C (-67F to +257F)
- a resolution of 0.02°C
- with a ±0.5% accuracy from 0°C-50°.
- only 1 IP address required for every 20* sensors.

- compact plug & play sensor.
- designed for indoor use.
- steel enclosure.
- industrial grade.
- 0u rack, DIN rail or wall mountable sensor.
- plugs into the base unit.
- powered by the base unit.
- alerts via SNMP Traps, email or SMS.
- integrates via Modbus TCP, SNMP, JSON with other systems.

Designed for rack monitoring
Daisy chained temperature & humidity sensors inside a data center
With this unique daisy chained sensors, data center operators can now start monitoring their racks at a lower cost of ownership compared to most wired and wireless solutions.

Using just one base unit and one IP address, up to 20 temperature & humidity sensors can be deployed inside your racks. Following ASHRAE standards, this means that with one single base unit you can monitor up to 20 racks.

No wireless & no battery problems
Wireless technologies like Zigbee suffer from unstable connections due to interference from Wifi and LED lights. Connectivity issues also drain batteries resulting in down time and an increased total cost of ownership.

With the daisy chained sensor you won't face radio or batteries issues: the sensor is connected using a wired cable connection and is powered by the base unit.

How It works.
Illustration showing the operation of the InfraSensing daisy chained temperature sensor


The DAISY-STARTER* sensor connects to the the base unit. Up to 20 additional DAISY-THUM sensors can be connected to the DAISY-STARTER using simple RJ45 cables. This makes the device an ethernet based temperature sensor to monitor temperature in up to 30* points inside racks. Alerting via email, SMS, voice call. Integrates with BMS platforms using the Modbus TCP protocol. Or with NMS systems through SNMP GET and SNMP TRAPS.
