What is it?

Introducing the "Energy-Harvesting Wireless Transmitter & Receiver" – a revolutionary solution exclusively designed for the seamless transmission of a single signal.

The transmitter cleverly captures energy via a specially designed button, optimized for energy harvesting. This button incorporates an inventive spring mechanism, efficiently capturing and releasing energy generated with each press. This energy is seamlessly directed to a coil, which subsequently powers the transmitter. The power generated is able to send a signal to the receiver that is a couple of meters away. See demo video below In the video, the blue LED is the pulse output and the red LED is the toggle output.

The receiver, on the other hand, is engineered for dependable performance using standard power sources. The receiver has the following pinouts:

• VIN: (3.3V)
• PLS: Pulse output - pressing the transmitter button will trigger a HIGH-then-LOW pulse to this pin. This could be used as an Interrupt for an external microcontroller or Arduino to do some useful work upon the press of a button. It could also be used to wakeup an MCU.
• TOG: Toggle output - pressing the transmitter button will toggle and latch the state of this pin. For example, if the previous state was HIGH, it will change it to LOW and vice versa. Since this is a latching state, the state will keep its value until the next button press.
• GND

Using a self-powered transmitter in situations where the receiver needs to be powered can offer distinct advantages, particularly in scenarios where you want to minimize maintenance, increase reliability, or enhance convenience. Here are some use cases where this approach can be advantageous:

• Emergency Signaling: In emergency situations, users can rely on the self-powered transmitter to send distress signals or notifications to the powered receiver. This ensures that even in critical moments when power sources may be disrupted, the transmitter can still function.

• Remote Activation: Users can remotely activate devices or systems in locations where power sources are available at the receiver but not at the transmitter site. For example, turning on outdoor lights, heating systems, or water pumps by pressing a button at a remote location without the need for complex wiring or battery replacements.

• Wireless Doorbell: Say goodbye to battery replacements and complex outdoor wiring for your doorbell with our energy-harvesting transmitter.

• Hobby and Educational Projects: Makers and students can explore the principles of energy harvesting and wireless communication through educational projects that involve self-powered transmitters. It offers an opportunity to learn about energy conversion and transmission technologies.
