OEM Wireless Light Sensor

The wireless light sensor detects the presence of light and returns a value of light or no-light to the system. This sensor can be used to alert when lights are left on or can be used to determine if cargo has been opened.

All sensor data is securely transmitted through an OEM wireless gateway to the iMonnit Online Sensor Monitoring software where it is stored and viewable from any web enabled device. The iMonnit online software system is completely white label (private brand) capable, allowing you to offer the online monitoring service as your own. Email and SMS text messages can be configured through the online system to alert users immediately when a defined parameter has been met or exceeded.
