Milesight Pulse Counter EM300-DI-868M

The Milesight EM300‑DI‑868M is a compact LoRaWAN®-enabled pulse counter designed to modernize traditional water meters into intelligent, remotely monitored devices. It is equipped with a dry contact GPIO interface, supporting both pulse counting and digital input detection, allowing it to interface with a wide range of passive pulse meters including reed switch-based meters.

With IP67-rated protection, it is well-suited for harsh indoor and outdoor environments. The built-in 4000 mAh replaceable battery (optional 8000 mAh) provides up to 5 years of operation with minimal maintenance, making it ideal for agricultural irrigation, industrial metering, and residential property management.

In addition to metering, the EM300‑DI includes integrated temperature and humidity sensors for environmental monitoring, as well as features like water flow/outage alarms, data logging (1,000 records), and data retransmission to prevent data loss.

Thanks to Milesight D2D protocol, the device supports direct control without gateways, offering ultra-low latency performance. It supports NFC-based configuration, cloud connectivity via Milesight IoT Cloud, and can be integrated with the Milesight Development Platform for advanced data visualization and automation.
