US915 LoRaWAN pulse transmitter for remote meter reading
The Comm. module EM300-DI US MS Pulse transmitter US Version LoRaWAN is a compact wireless pulse counter for converting traditional pulse-output meters into remotely readable LoRaWAN devices. This version supports the US915 frequency plan for compatible installations in North America.
The EM300-DI can be connected to passive pulse meters such as water, gas, electricity and heat meters. Pulse data is transmitted through LoRaWAN to a compatible US915 LoRaWAN gateway and monitoring platform for consumption tracking, alarms and historical analysis.
Pulse counting and environmental monitoring
The device provides one dry-contact GPIO input that can operate as a pulse counter or digital input. It supports pulse frequencies up to 2,000 Hz and can calculate water consumption and generate water flow or outage alarms.
Integrated temperature and humidity sensing provides additional environmental data. The device stores up to 1,000 historical records and supports data retransmission to help prevent data loss during temporary network interruptions.
Configuration is performed through NFC using the Milesight ToolBox app or remotely through LoRaWAN downlink. See the official Milesight EM300-DI product information and documentation for detailed specifications.
