Standard Temperature Sensors

Monitor the temperature of virtually anything.

Remote temperature monitoring continues to be the most popular Internet of Things (IoT) solution across many use cases. Global enterprises trust Monnit ALTA® Standard Temperature Sensors to protect equipment, inventory, and personnel.

It’s critical to know the temperature of a wide variety of things like food, motors, coolers, rooms, water, trucks, grow houses, and more so you can predict maintenance and prevent problems. Monnit Sensors issue an alert via text, email, or call when the temperature exceeds preset thresholds set in cloud-based software.

Ranging from a compact wireless coin cell (CC) battery-powered unit to a Power over Ethernet (PoE) sensor to an intrinsically safe, IECEx-certified temperature sensor, there’s a temperature monitoring solution for many industry applications and nearly any business or facility.

Common & Uncommon Temperature Sensor Uses

Tailor an ALTA Wireless Standard Temperature Sensor to a specific need to measure temperature between -40°C and 125°C (-40°F and 257°F) with optional probes ranging from 3–100 feet. Monnit Labs can also create custom temperature sensors for your unique application or use case. If you're looking to monitor temperature and humidity, browse our temperature and humidity sensors.

Which Sensor is Right For Me?

  • Enterprise AA-battery powered: Our most popular type is ideal for typical commercial and enterprise environments, such as server rooms. A 2,000+ ft. through 18+ walls wireless range when connected to an ALTA XL® Gateway readily covers most facilities.
  • CC-battery powered: The compact sensor is great for space-restricted areas such as control cabinets or cold storage.
  • Industrial: The sensor's weatherproof, NEMA-rated enclosure withstands demanding indoor/outdoor use, e.g., warehouses and production facilities.
  • ALTA-ISX: Approved for industrial applications or use cases in potentially hazardous areas with explosive atmospheres.
  • PoE•X: Power over Ethernet sensors integrate with a building's PoE network; it can also be used with a standard Ethernet infrastructure and powered via an optional AC adapter.
  • MoWi WiFi: This discreet sensor uses your Wi-Fi for networking and data transmission—popular for smaller businesses and facilities.
