iSense Solar Power Harvesting System

The iSense Solar Power Harvesting System is an out-of-the-box solution for running self-powered wireless sensor networks. By harvesting solar energy and storing it in a rechargeable battery, it allows to operate sensor nodes all-time autonomously.

The iSense Solar Power Harvesting System consists of a solar panel, an ultra-high capacity lithium ion rechargeable battery, a power management module and a sensor node housing.

The power management module distributes the power provided by the solar panel in an intelligent way. If the panel can deliver more power than the sensor node requires, it charges the lithium ion battery (a). Otherwise, it reduces the battery drainage by partially supplying the node with the solar power (b).

When power is supplied to the connected iSense Core Module via USB or a wall mount adapter, the battery is automatically charged (c).

Additionally, an integrated battery monitor provides precise information on the energy currently stored in the battery, accumulating both charging and discharging cycles, as well as information regarding the battery voltage, the current consumption and temperature.

Combined with an iSense Core Module and iSense Sensor Modules, self-powered sensor nodes can be plugged together. The housing provides enough space for up to three iSense Modules, plus the iSense Solar Power Management Module.
