Seemoto Sensors

All Seemoto sensors are wireless, battery-powered IoT devices.
They measure temperature, humidity, and other environmental conditions in real time or offline.

Sensors communicate securely with any nearby Seemoto gateway, creating flexible and scalable monitoring networks.
Each sensor is easy to install, maintenance-free, and compliant with global cold chain regulations.

Collected data is sent to the Seemoto cloud platform.
Users can access this data via web and mobile interfaces, or integrate it with ERP and quality systems through API.
