The Basic Gen2 900 MHz Wireless Pulse Counter - 1 Input - can be integrated with a water or power meter that provides a pulse output to count the number of actuations occurring within a given time frame. The pulse counter is by default, set-up to operate with signals that are less than 10Hz.  Through software it can be changed to a maximum of 20Hz.

Features:

• 900MHz Operating Frequency
• Wireless range of 1,200+ feet through 12+ walls *
• Frequency-Hopping Spread Spectrum (FHSS)
• Improved interference immunity
• At 1 hour heartbeat setting, coin cell battery will last ~ 1-2 Years***
• Encrypt-RF® Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages)
• Datalogs 2000 to 4000 readings if gateway connection is lost
• Over-the-air updates (future proof)
• Counts the number of pulses in given time frame, or ag­gregates pulses in an on-going accumulation
• Capable of counting passive (open/closed switch) and active (Up to +15 VDC) pulses
• Capable of counting the positive edge, negative edge, or both edges of a pulse
• The software also has multilevel passwords and the highest level encryption to meet 21CFR part 11 compliance
  
• Mounting Tape & Mounting screws included

Specifications:

* Actual range may vary depending on environment

**Hardware cannot withstand negative voltage. Take care when connecting a power device

*** Battery life is determined by sensor reporting frequency and other variables
