The DFRobot DFM8001 indoor ambient power harvesting equipment can energy IoT gadgets through the use of photo voltaic power, and the corporate says it may well additionally harvest mechanical, thermal, and RF power from the native setting however there isn’t any means that equipment can do this with out extra {hardware}.
The DFRobot equipment consists of an analysis board with the corporate’s DFM8001 power harvesting module, two pluggable supercapacitors, and a photo voltaic panel used as energy enter. You also can use different sources that emit a minimum of 150 mV that accumulate power from RF, thermal, or mechanical sources. The board has two outputs a low-voltage (1.2-1.8V) terminal as much as 20mA, and a high-voltage (1.8V-4.1V) terminal as much as 80mA, and two battery connectors and a few jumpers for configuration.
Details of DFM8001 power harvesting equipment:
- Operating voltage – 3.3V to five.5V DC
- Cold begin situation – Input > 400mV 15uW
- Continuity voltage after chilly begin – 150mV.
- Input voltage vary – 150mV – 5V by way of 2-pin SRC SA terminal block
- MPPT ratio – 70%, 75%, 85%, 90% (adjustable)
- MPPT computerized detection frequency – 5 instances per second
- Dual LDO voltage regulation output
- 2-pin Low voltage terminal – 1.2 to 1.8V as much as 20mA (enabled / blocked by jumper), for instance for low-power MCU board
- 2-pin High voltage terminal – 1.8 to 4.1V as much as 80mA (enabled/disabled by jumper), for instance for low-power RF receiver
- Energy storage administration
- 1.5F and 0.22F supercapacitor power storage modules (linked by way of 4-pin + 3-pin header)
- 2-pin PRIM terminal block for major battery
- 3-pin BAT terminal block for exterior power storage gadgets with +, -, and DCSC.
- Adjustable overcharge safety – 2.7V – 4.5V
- Adjustable over-discharge safety – 2.2V – 3.6V
- Low battery warning
- LDO output out there indicator
- Switch to backup battery after 600ms
- Supports disposable backup battery
- Solar panels
- Maximum energy level – 70%
- Maximum energy – 90uW @ 200Lux
- Dimensions
- Module – 15 x 15 x 3.5 mm
- Evaluation board – 57 x 42 mm
- Amorphous silicon photo voltaic panel – 45 x 45 mm
- Temperature Range (for DFM8001 module solely) – Operating: -40°C to +125°C; storage: -40°C to +150°C
The documentation for the analysis equipment could possibly be higher, however I imagine that is sufficient to get began. You also can discover one other wiki for the DFM8001 module particularly. The firm says that other than the essential amorphous silicon photo voltaic panel offered within the equipment, customers can use larger effectivity photovoltaic panels corresponding to natural or dye-sensitized photo voltaic panels.
Typical functions embrace indoor lighting power harvesting, self-powered Internet of Things (IoT) nodes, Smart Home programs, industrial monitoring, asset administration, and Ambient IoT. DFRobot sells the DFM8001 indoor ambient power harvesting equipment for $16.90. You also can purchase the DFM8001 module by itself for $4.90.
