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°.
- up to 40* temperature sensors per base unit.
- only 1 IP address required for every 40* sensors.
- powered by the base unit.
- 0U Rack mountable sensor.
- alerts via SNMP Traps, email, SMS or voice calls.

*40 limit depends on configuration. It can be increased for large orders to 60 using a special firmware. Requires minimum purchase of 1,000 sensors

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 40+ temperature sensors can be deployed inside your racks. Following ASHRAE standards, this means that with one single base unit you can monitor up to 10 racks. Following other practices you could even go up to 20-30 racks with just one base unit.

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 ENV-TEMP-START* sensor connects to the the base unit. Up to 40 additional ENV-TEMP-DAISY sensors can be connected to the ENV-TEMP-START using simple RJ45 cables. This makes the device an ethernet based temperature sensor to monitor temperature in up to 40* 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.

The ENV-TEMP-START can be used to for both the ENV-TEMP-DAISY or the ENV-THUM-DAISY.
