by The Leading Enterprise Internet of Things Solution Wireless Pulse Counter - Single Input General Description Features of Monnit ALTA Sensors The ALTA wireless pulse counter can be connected to Wireless range of 1,200+ feet through 12+ walls * the pulse output of a system (water meter, power meter, Frequency-Hopping Spread Spectrum (FHSS) etc.) to count the number of actuations within a given time Improved interference immunity frame. Improved power management for longer battery life ** (12+ years on AA batteries) Counts the number of pulses in given time frame, or Encrypt-RF Security (Diffie-Hellman Key Exchange aggregates pulses in an ongoing accumulation. + AES-128 CBC for sensor data messages) 3 filter settings: No filter, 4 Hz filter, and 40 Hz filter. Datalogs 2000 to 4000 readings if gateway connection Capable of counting passive (open/closed switch) and is lost (non-volatile flash, persists through the power active (Up to +15 VDC) pulses. cycle): Capable of counting the positive edge, negative edge, - 10-minute heartbeats = ~ 22 days or both edges of a pulse. - 2-hour heartbeats = ~ 266 days Over-the-air updates (future proof) Free iMonnit basic online wireless sensor monitoring Principle of Operation and notification system to configure sensors, view data and set alerts via SMS text and email The ALTA wireless pulse counter is an electronic counter capable of counting passive(open/closed switch) or active Actual range may vary depending on environment. * (Up to +15 VDC) pulses. The counter includes 3 software Battery life is determined by sensor reporting ** configurable low pass filter settings (No filter, 40 Hz filter, frequency and other variables. Other power options or 4 Hz filter). The pulse counter filters pulses with pulse are also available. widths greater than those designated in the technical specifcations. For example, if the 4Hz filter is set, the Wireless Range Comparison pulse counter will count a pulse if the pulse width is longer than 250 ms, if the pulse width is shorter than 250 ms it Wireless Range Comparison will be completely or partially filtered (See the Technical Monnit ALTA Specification table for detailed filtering information). The sensor can be set to send an alert through the iMonnit Online Sensor Monitoring and Notification System when a given number of pulses have been reached within a set Monnit time frame. Alerts from the iMonnit system are sent as they happen (in real time) via SMS text or email.

Take care when connecting a power device. At temperatures above 100C, it is possible for the board circuitry to lose programmed memory. ** *** Low Pulse: 0 Volts to 0.2 * VBatt, High Pulse: 0.8 * VBatt to 15 Volts. High pulse count rates can impact battery life. AA battery powered sensors are recommended if counting pulses faster than 1x per second. **** ***** Input pulse rate must be less than specified Max Pulse Rate and input pulse width must be greater than specified Min Pulse Width to ensure the input pulse is counted.
