Description
The YO Meter (pulse) input accepts connection to potential-free contacts. The device will not count pulses if the input is connected to contacts with any potential. Device input can detect pulses with different contact debounce times. This parameter is configurable and by default is 47 ms – up to max. 10 pulses per 1 s (boundary range 1-50 pulses per 1 s depends on the contact debouncing setting).
Device is equipped with two counters: periodic and persistent. Periodic counter counts pulses cyclically with time interval defined by LoRa sending interval. Persistent counter accumulates pulses and stores them in non-volatile memory - this counter can be reset (cleared) using one of the parameters via BLE.
Based on the data collected by the device, it is possible to collect the number of pulses from measuring devices, for example, from water meters.
YO Meter (Pulse) features a IP67 protected enclosure and battery power supply.
YO Meter (Pulse) operates on LoRaWAN. We are a member of the LoRa Alliance, which is responsible for data transmission security.
