Wireless digital sensor with battery-free renewable power supply

Abstract

The invention relates to a wireless digital sensor with a battery-free renewable power supply, comprising a microprocessor unit, a sense unit, a wireless radio-frequency emission unit, an energy unit and an energy collection and management unit, wherein an energy output unit is connected with an input end of the energy collection and management unit; the output end of the energy collection and management unit is connected with a power supply end of the microprocessor unit; an input end of the microprocessor unit is connected with a data signal output end of the sensing unit; the output end of the microprocessor unit is connected with the wireless radio-frequency emission unit; and the energy unit can pick up multiple energies which can be converted into teeny current and voltage, and the energy collection and management unit collects and stores the teeny current and voltage to supply electricity for a sensor. The invention has the benefit effects that 1) various energies (such as mechanical energy, luminous energy and electromagnetic energy) in different scenes are collected and converted into electric energy to be stored; 2) the signals input by the sensor are analog quantity and digital quantity; and 3) the sensor of the invention can work without a dry battery or additional power supply for supplying the electricity.

Description

technical field [0001] The invention relates to the field of wireless digital sensors, in particular to a wireless digital sensor that does not need dry batteries or external power sources without battery regeneration. Background technique [0002] At present, the global energy is depleting day by day, and the global warming caused by carbon dioxide emissions poses a major threat to the environment and ecology. The sustainable use of energy and the balance of environmental protection considerations have long become the consensus of all countries. To actively develop clean renewable energy, it is necessary to emphasize the improvement of conversion efficiency in the use of energy, and use the synergistic effect of the two to create the best energy use environment. [0003] Many low-power industrial sensors are gradually switching to alternative energy sources as the main or auxiliary power supply from the original external power supply. Ideally, this harvested energy would e...

Problems solved by technology

[0004] At present, almost all wireless digital sensors use dry batteries as the power source. Due to the high power consumption of the circuit, the service life of the dry batteries is very short, and they need to be replaced in time, which increases the management and cost of production, and because the scrapped dry batteries are inconvenient. Recycling causes waste of resources and pollution of the environment
