Data Acquisition & Logging
Wireless Button Press Sensor
The ALTA Wireless Button Sensor detects when the button has been pressed triggering a notification from the system.
• Detects when button is pressed
Principle of Operation
The ALTA Wireless Button Sensor sends a signal to the iMonnit Online Sensor Monitoring and Notification System when the button is pressed triggering a notification via SMS text or email and tracking the data in the online system and can be reviewed and exported as a data sheet or graph. Notifications can be set up through the online system to alert the user immediately when movement is detected 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.
