HW group STE2

WiFi temperature and humidity sensor with two digital inputs for dry contacts. Connects to the network via WiFi or Ethernet with PoE (802.3af) support. STE2 wifi thermometer is supplied with a power adapter and a temperature probe. STE2 wifi and ethernet thermometer supports SNMP. STE2 online thermometer can be connected to the SensDesk online portal or to a SMS gateway.

Three external temperature or humidity sensors can be connected to the STE2 wifi thermometer. The two green Digital Inputs can be used to connect e.g. a dry contact door sensor. Sensor readings and detector states can be monitored over the WEB interface to achieve an online thermometer solution. Text message (SMS) or email alert is sent if the temperature exceeds a specified limit or a contact is closed. A separate product, SMS gateway, is used to send text messages. Supports secure TLS email (SMTP TLS).

Software a online portal

• STE2 wifi temperature monitor supports SNMP.
• With the HWg-PDMS software for Windows, data can be displayed in graphs and exported to MS Excel.
• STE2 wireless thermometer can be connected to the SensDesk.com online portal (and a mobile app).

Typical applications

• STE2 wlan thermometer is an ideal solution for wireless temperature monitoring in storages or coolers.
  WiFi interface allows for a fast and easy installation. We supply a wide range of humidity and temperature sensors.
• STE2 wifi thermometer sends an e-mail if a temperature is too high or a door is open (dry contact connected to a digital input is closed).
• STE2 is frequently used as a remote temperature sensor wifi / remote temperature monitoring device for remote environment monitoring and temperature alerts, e.g. in a computer room or a production facility.
  Digital inputs can be easily connected to a smoke detector, flood detector, door sensor, window sensor, vibration detector, PIR motion detector, and more.

Usage examples

• Remote environment monitoring in laboratories
  Wifi temperature monitoring at remote locations, without network cables.
  
  
• Remote monitoring of environment and machinery in industrial production
  Temperature monitor for machines, digital inputs detect the states of the machines. Can be connected to a central SCADA monitoring system. Thanks to the wireless link, the wifi temperature monitor can be placed anywhere at the production facility.
  
  
• Freezer/cooler monitoring
  Our special temperature sensors for use in refrigerators monitor the temperature in freezing and cooling compartments. The digital thermometer can monitor the storage of medicaments, meat, or other foodstuffs.
  Sends a TLS email alert if the refrigerator door is open for too long, or the temperature is too high or too low. Logging in the PDMS application or the SensDesk online service.
  
  
• Remote A/C monitoring
  STE2 wifi thermometer monitors the temperature at the air conditioner outlet. Detects A/C malfunctions or power outages.
  Rising temperature points to a failure of the A/C unit.
  
  WiFi temperature and humidity sensor with two digital inputs for dry contacts. Connects to the network via WiFi or Ethernet with PoE (802.3af) support.
  
  
• Environment monitoring, power outage detection
  Server room temperature sensor function. Thanks to PoE ieee 802.3af support, the wifi termometer can be powered from a UPS and works even if the power is out.
  
  
• Surveillance (camera) systems
  Sensor readings and detector states can be fed to IP camera systems of various brands.
  External detectors (door contacts, PIR, smoke detectors etc.) can be connected to the digital inputs of the STE2 wifi thermometer.
  
  
• Temperature monitoring at several places
  Several STE2 units can be linked to a single account at the SensDesk.com online portal. All readings are accessible anywhere using a web browser or a mobile app for Android and Apple.
  
  
• Food storages
  Oversees optimal storage conditions. With application software, HACCP reports can be created.

Cooler/freezer wifi monitor

• Wireless temperature monitoring – easy installation
• Remote cooler temperature monitoring
• Remote freezer temperature monitoring
• Flat-cable temperature sensors are placed in the deep-freezers and coolers. The installation is simple, the cable leads by the door seal.
• The door contact alerts to improperly closed door
• SNMP thermometer, can be linked to any software
• Email or SMS can be sent if the door is open for longer than 3 minutes
  
• HWg-PDMS can be used for long-term logging
• SensDesk.com portal can be used to check the temperature from anywhere, anytime

Remote environment and machinery monitoring in industrial production

• Wireless temperature monitoring anywhere at the site – fast installation
• Monitoring of temperature, humidity, door contacts or other detectors (smoke, power failure etc.)
• STE2 wifi thermometer can be connected over a LAN and powered using PoE
• SNMP temperature monitoring with any software (list of third-party SW)
• Email or SMS can be sent if the door is open for longer than 3 minutes
  
• SMS gateway can be used to send text message alerts
• SensDesk.com portal can be used to check the temperature from anywhere, anytime
• HWg-PDMS can be used for long-term logging

LAN and WiFi connection to the network

• STE2 wireless temperature sensor can be connected to the network over WiFi (2.4 GHz) or Ethernet (RJ45).
• STE2 can be also powered over the Ethernet – PoE 802.3af.
• When using LAN and WiFi at the same time, the IP thermometer will be accessible at two different IP addresses.
• When using PoE, the humidity and temperature sensors are also powered over the Ethernet.
• Digital inputs do not provide power to the detectors.
• We recommend the SensDesk.com online portal for remote monitoring of the wireless temperature sensor with the connected sensors and detectors.
• For the SensDesk portal, mobile apps for sensor and detector monitoring are also available.

Text message (SMS) alerts

Alert SMS can be sent from the STE2 wireless thermometer in several ways:

• Directly over the network using SMS-GW
  A text message can be sent from the STE2 temperature monitor to a specified phone number using the HWg-SMS-GW3 unit.
  No software is needed. HWg-SMS-GW should be connected to the same LAN. Sender´s phone number is defined by the SIM inserted in the HWg-SMS-GW3 unit. Recipient´s phone number is configured in the STE2 web interface, similarly to e-mail recipients.
  One HWg-SMS-GW3 gateway can be shared by several devices.

• With the HWg-Trigger application for Windows
  The HWg-Trigger application can run in the background on any PC with MS Windows. The application checks for device failures, disconnected sensors, or sensor readings outside of the Safe Range. Alarm status can be notified e.g. by sending a SMS to a specified number using a “HWg-SMS-GW3” in the same LAN.
