Temperature & Humidity Sensors

Temperature sensors act as preventative warning systems that determine whether there are impending risks or malfunction. Overheating detection plays crucial role in many systems, thus protecting from major disasters like fire. Temperature sensors which are now affordable and easy to use may prove very effective in early alarming and prevention.

All NXS-family of SMSEagle devices is equipped with internal temperature and humidity sensor. The internal sensor allows to measure temperature with ±0.5°C accuracy and humidity with ±2% RH accuracy.

Additionally, NXS-97xx Rev.3 (and higher) devices also support external sensors via 1-Wire interface.
A measured values from sensors can be displayed in Web-GUI of SMSEagle and used to trigger SMS message to single/many recipients.

Reading temp/humidity via SNMP protocol

Current temperature and humidity values from internal sensor can be also read via SNMP protocol. See chapter “SNMP agent” in user’s manual for details.

Connecting an external temperature sensor

External probes with temperature sensors for SMSEagle NXS-97xx Rev.3 (and higher) devices can be purchased in our online store or via Sales Partner network. The purpose of the probes is to facilitate temperature measurement and SMS alerting via “Temp & humidity” menu in SMSEagle Web-GUI.

Multiple sensors are supported and can be attached in parallel.
Once attached to the device you need to “Scan for sensors” in Temp & Sensors > Settings menu
