4G Cellular Contact Sensor – Solar Powered

The Solar-Powered 4G Cellular Dry Contact Sensor provides real-time monitoring of open/close states, switch activity, and contact duration in remote or standalone locations where LoRaWAN is not available. Built for industrial and agricultural environments, this unit uses 4G LTE (Cat-M1/NB-IoT) to deliver reliable telemetry anywhere with mobile coverage.

The sensor detects contact open/close, counts how many times the state changes, measures how long the contact remains open, and sends this to the cloud. It supports event-based alerts, scheduled reporting, and configurable behaviour to suit automation, security, and control applications.

A built-in 3000mAh rechargeable Li-ion battery paired with a high-efficiency solar panel ensures long-term autonomous operation, even in low-light locations.

Designed for outdoor deployment, the IP67 enclosure protects the electronics against dust, rain, and extreme weather. The device is fully compatible with ProSight, AWS IoT, Azure IoT, custom MQTT platforms, and third-party cloud dashboards.
