DFM8001 Ambient Energy Harvesting Module for Indoor IoT Battery-free Devices

Harness the power of the natural environment with the DFM8001 Ambient Energy Harvesting Module. This module is a micro-energy harvesting module that can be used indoors. It efficiently collects and stores energy from abundant sources such as mechanical, thermal, solar, and radio frequency energy. The best part? It does not require a battery, eliminating the need to worry about charging, discharging, and battery life.

Energy sources in the natural environment are influenced by factors such as geographical location and weather, making it difficult to utilize effectively due to their weak and unstable characteristics. The DFM8001 module addresses this challenge by being capable of handling energy ranging from weak to microwatt levels. It features dynamic MPPT tracking, which regularly monitors the status of input sources and adjusts to the maximum power point to ensure efficient collection of weak energy. Moreover, the module integrates functions including charge and discharge management, energy storage management, and dual-channel voltage stabilization output.

The DFM8001 module integrates necessary components for operation internally. Simply connect the module’s configuration pins to GND/Vbuck, and connect energy harvesting devices, energy storage devices, and electrical devices to construct an ambient energy supply system. It is particularly suitable for use with amorphous silicon, organic materials, dye-sensitized, and other types of photovoltaic cells, exhibiting excellent energy storage performance even in weak light environments such as low sunlight or indoor lighting.

For user convenience, DFRobot has introduced the DFM8001 Evaluation Kit. This kit includes the DFM8001 evaluation board, amorphous silicon photovoltaic cells, and a supercapacitor energy storage module. Users can build an ambient energy power system with a simple connection.
