ATEK LoRaWAN Digital-Input / Pulse-Counter Sensor (EM300-DI)

The ATEK EM300-DI is a battery-powered LoRaWAN Class A sensor with one dry-contact digital input that runs as a pulse counter or open/closed status monitor — ideal for utility metering, leak contacts, and door/window status.

• One dry-contact GPIO input: pulse counting up to 2,000 Hz (250 µs min. pulse width) or open/closed status on the same channel
• Turns reed-switch and passive water/gas meters into wireless meters; digital filtering for drift-free counts with flow/outage alarms
• Embedded temperature & humidity sensing for ambient monitoring alongside the counter
• IP67 flame-retardant enclosure; 1,000-entry buffer with retransmission; NFC mobile-app setup
• Up to 5-year life on a replaceable 4,000 mAh Li-SOCl2 cell (8,000 mAh option); LoRaWAN bands EU868 / US915 / AU915
