Data Acquisition & Logging

Wireless Open/Closed Sensors

Description Features Configuration Application

The ALTA Wireless Open/Closed Sensor can be used to detect when a door or window is opened and closed using a magnetic switch.

• Detects when a door or window is accessed.

• Uses magnetic detection switch.

Principle of Operation

The ALTA Wireless Open/Closed Sensor uses an external magnetic switch to detect the presence or removal of a trigger magnet. When the sensor detects that the magnet is removed or returned it sends the information to the iMonnit Online Sensor Monitoring and Notification System. The data is then stored in the online system and can be reviewed and exported as a data sheet or graph. Notification alerts can be set up through the online system to alert the user when a magnetic source is present or not with the ability to only notify within time of day parameters.

• Wireless range of 1,200+ feet through 12+ walls *

• Frequency-Hopping Spread Spectrum (FHSS)

• Improved interference immunity

• Improved power management for longer battery life ** (12+ years on AA batteries)

• Encrypt-RF® Security (Diffie-Hellman Key Exchange +AES-128 CBC for sensor data messages)

• Onboard data memory stores up to 512 readings per sensor:

-10-minute heartbeats = 3.5 days

-2-hour heartbeats = 42 days

• Over-the-air updates (future proof)

• Free iMonnit basic online wireless sensor monitoring and notification system to configure sensors, view data and set alerts via SMS text and email

*Actual range may vary depending on environment.

**Battery life is determined by sensor reporting frequency and other variables. Other power options are also available.
