The Sense IoT wireless pulse counter is an electronic counter capable of counting passive(open/closed switch) or active (Up to +15 VDC) pulses. The counter includes 3 software configurable low pass filter settings (No filter, 40 Hz filter, or 4 Hz filter). The pulse counter filters pulses with pulse widths greater than those designated in the technical specifications. For example, if the 4Hz filter is set, the 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 will be completely or partially filtered (See the Technical Specification table for detailed filtering information). The sensor can be set to send an alert through the Sense IoT Online Sensor Monitoring and Notification System when a given number of pulses have been reached within a set time frame. Alerts from the Sense IoT system are sent as they happen (in real time) via SMS text or email.
