Description
Technical field
The present invention relates to air quality detecting device.
Background technology
The today being on the rise in environmental pollution, more people pays close attention to air quality and people's the direct relation of health.But existing air quality analyzer, often needs battery supply of electrical energy, the air quality analyzer that lacks battery cannot be worked; So cause air quality analyzer to be not easy to carry because battery needs certain volume, high in cost of production characteristic.
Near-field communication---NFC(Near Field Communication), claim again wireless near field communication, be a kind of short-range high frequency wireless communication technology, allow to carry out contactless Point-to-Point Data Transmission (in ten centimetres) swap data between electronic equipment.NFC information and electric energy are to transmit by the electromagnetic induction coupling scheme of wireless frequency part in frequency spectrum, and this makes low-power equipment by NFC equipment, to provide electric energy in the situation without self power supply.Novel mobile phone is all furnished with NFC interface now.
Summary of the invention
The object of the invention is needs battery to supply with electric weight in order to solve existing air quality analyzer, lacks the problem that battery air mass-synchrometer is difficult to work, provide a kind of based on NFC the air quality detector without battery.
Air quality detector based on NFC without battery, it comprises NFC main equipment, it also comprises Detection of Air Quality unit, Detection of Air Quality unit comprises processor, NFC module, sensor circuit, gas sensor and antennal interface, the output terminal of the transducing signal of gas sensor is communicated with the input end of the transducing signal of sensor circuit, the output terminal of the transducing signal of sensor circuit is communicated with the input end of the transducing signal of processor, the transducing signal output terminal of processor is communicated with the transducing signal input end of NFC module, the electric energy output end of NFC module is communicated with the electric energy input end of processor, antennal interface is communicated with the output terminal of the wireless signal of NFC module.
The present invention utilizes NFC main equipment that electric energy is provided, and does not therefore need powered battery, also can complete Air Quality Analysis.And partly transfer to NFC main equipment to go to process testing result demonstration, information processing, power supply supply etc., greatly reduce cost, the volume and weight of air quality detector, and integral body has the advantages such as fast response time, display effect are good.
