LoRaWAN Dry Contact Sensor – Pulse Counter with Temp & Humidity Monitoring

The LoRaWAN Dry Contact Sensor is a multi-functional device designed to detect dry contact status, count pulses, and monitor environmental conditions—all with long-range LoRaWAN communication. It features a 3-wire interface (VCC/GND/INT) and a 1-meter external cable for flexible deployment in access control, flow metering, or contact-based event logging.

In addition to detecting open/close states and counting pulses, the device includes a built-in temperature and humidity sensor to provide ambient condition data. It also supports an open alarm function, allowing immediate alerts when a contact remains open beyond a user-defined threshold.

Equipped with a 2400mAh internal battery, the sensor is designed for up to 10 years of operation*, making it ideal for unattended installations. The device also features a datalogging function, storing sensor readings when offline and automatically uploading them when network connectivity is restored.

Fully compatible with LoRaWAN v1.0.3 Class A, it integrates seamlessly with standard gateways and supports remote configuration and firmware upgrades.
