GSM Thermometer with E-mail (GPRS) and SMS alertsAres

  • Internal battery can supply power to HWg-Ares12 and its connected sensors for several hours.
  • Comfortable configuration over USB simplifies installation of the unit.
  • Remote firmware upgrade (FOTA) capability simplifies management of large-scale installations with hundreds of devices.
  • The "HWg-Ares12 Tset" quick start set contains a temperature sensor, an universal power adapter and an external antenna.
  • Whenever a power outage or a sensor value outside of a specified range is detected, Ares12 rings a specified number and sends a customizable e-mail or text message.
  • HWg-Ares is ready for data transfer over IP (GPRS) to third-party systems.

Ares: Environment monitoring over GSM/GPRS


  • HWg-Ares is a telemetry device suitable for integration with third-party central/portal solutions.
  • With the HWg-PDMS software, Ares can offer an instantly usable data collection solution.
  • Data outputs include logs+MS Excel analysis or a XML database.
  • Data collection over GSM with Ares can be combined with other IP sensors by HW group (Poseidon, Damocles, HWg-STE, HWg-PWR, and more).
  • Ares supports the same RJ11 sensors as the Poseidon family.
  • SMS notification of up to 5 recipients is advantageous for simple applications.
  • Text messages can be customized with macros.
  • Sensor or device status can be requested by texting or calling the device.
  • Configuration software needs no installation. Simply run the Windows application from the USB drive that appears after connecting Ares to an USB port.
    • The internal battery enables alerting to failed/restored power supply. Suitable for monitoring UPS and back-up generators.
    • Roaming functions reduce data costs outside of the home GSM network. Suitable for automotive or marine applications.
