The Monnit ALTA wireless temperature sensors use a thermistor to accurately measure temperatures. These sensors are perfect for monitoring ambient temperatures around the sensors physical location. User customization allows you to set the frequency of readings and the ability to set thresholds for alerts via SMS text and/or email. The Temperature Sensor is not meant for wet, damp, high humidity environments

The general purpose AA model should only be operated in dry, low humidity environments. Should you need a temperature sensor that operates at extreme temperatures and can withstand getting wet or condensed on, please consider the IP65 NEMA 4X model.

Important Note: Monnit Alta wireless sensors must be paired with a Monnit Alta gateway in order to have a working system. One Serial Modbus gateway can support up to 50 sensors and one Ethernet, USB, or Cellular gateway can support up to 100 sensors. Monnit Alta gateways can be found on the accessory tab.

looking at what it would take to monitor hydraulic oil pump systems and cooling water on multiple pumps inside one building. Does this have the ability to have more than 5 ft temperature leads on some units? Does this transmit from multiple units?

Asked by: Dennis R
Hello Dennis You will need to get an Alta Wireless Gateway to communicate with it wirelessly, the gateway can monitor up to 100 wireless Alta series transmitters. At the time they only come with 3 ft probes.
