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 -55°C to +125°C (-67ºF to +257ºF)
- a resolution of 0.02°C
- with a ±0.5% accuracy from 0°C-50°.
- only 1 IP address required for every 20 temperature sensors.
- up to 100m/300ft length for daisy chain sensors.
- longer length possible with optional DAISY-BOOSTERS.

- compact plug & play sensor.
- designed for indoor use.
- steel enclosure for non-power sensors or non-IP sensors. custom color & logo options available.
- industrial grade.
- 0u rack, DIN rail, magnetic or wall mountable sensor.
- plugs into the base unit.
- powered by the base unit (PoE, 12v DC, optionally 24v or -48v)
- alerts via SNMP Traps, email or SMS.
- out of the box integration via Modbus TCP, SNMP.
- optional integration via MQTT for Industrial IoT applications1New feature.
- optional integration via RS-485 enabling direct integration with your own gateway & controllers.2New feature

1Requires FW 10 or higher
2Some sensors are not available in RS-485 native versions. In that case RS-485 is available using the optional Modbus RTU module.

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 sensors can be deployed inside your racks. Following ASHRAE standards, this means that with one single base unit you can monitor up to 3 racks with 6 sensors per rack.

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.
No wireless sensors

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-TEMP 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.
