MCF-LW06CNT LoRaWAN Class C pulse counter/frequency meter MCF-LW06CNT is a LoRaWAN™ interface with an opto-isolated digital input that can be used to count pulses or measure a frequency up to 2KHz from 5V to 36V. This enables the reading of any device with a pulse output interface or the measurement of frequency or speed, e.g. tachometers, flow meters, electronic volume correctors (EVC), gas flow meters, fan speed, air flow measurement, etc. Special features
