OVERVIEW
Protect your equipment, inventory, and personnel with Monnit standard temperature sensors
Global enterprises trust Monnit Enterprise Standard Temperature Sensors to protect equipment, inventory, and personnel. This sensor sends readings to iMonnit Online Wireless Sensor Monitoring and Notification system in degrees Fahrenheit or Celsius based upon your configurations. When the temperature exceeds preset thresholds, these sensors issue an alert via text, email, or call.
The Temperature Sensor uses a type Negative Temperature Coefficient (NTC) thermistor to measure temperature. It is accurate to ± 1° C (± 1.8° F) and accuracy can be increased by user calibration to ± 0.25° C (± 0.45° F).
Monitor the temperature of virtually anything
The Enterprise Standard Temperature Sensor outputs the ambient temperature in degrees Fahrenheit or Celsius. The sensor’s programmed to sleep for a user-given time interval (heartbeat) and then wake up. Then, it sends power to the NTC thermistor and waits for it to stabilize to convert the analogue data, mathematically compute the temperature, and transmit the data to the gateway. The sensor’s processor is programmed to calculate the temperature based on an internal data table. The Temperature Sensor also implements and configures a variable resistor over specified temperature ranges to reduce error. An industry-leading 25-month NIST certification is available on leaded Monnit Temperature Sensors.
This sensor comes with two replaceable AA sized batteries and the sensor has a typical battery life of up to 10 years. It can also be customised with an additional probe in lengths ranging from 3 – 100 ft.
Features:
- Impressive wireless range of up to 1,200 feet through walls
- Frequency-hopping spread spectrum (FHSS)
