Formaldehyde detector based on WIFI

Abstract

The invention discloses a formaldehyde detector based on WIFI. The detector comprises a single-chip processor, a formaldehyde sensor, a temperature sensor, a humidity sensor, a signal modulating circuit, a heating and lighting control circuit, a sound and light alarming circuit, and a wireless WIFI communication module; the formaldehyde sensor, the temperature sensor, and the humidity sensor are all connected to the single chip processor through the signal modulating circuit; the temperature sensor is arranged on the formaldehyde sensor; the single chip processor is connected to the input terminal of the heating and lighting control circuit; the output terminal of the heating and lighting control circuit is connected to the formaldehyde sensor; the single chip processor is connected to the sound and light alarming circuit; and the single chip processor communicates with a mobile phone terminal through the wireless WIFI communication module. The detector is excited by ultraviolet lights and a heating temperature of 75 DEG C to carried out formaldehyde collection, has the advantages of high sensitivity and good collecting effect, is convenient for users to observe the indoor formaldehyde concentration, is low in cost, is easy to promote, and has a very good application prospect.

Description

technical field [0001] The invention relates to a wifi-based formaldehyde detector and belongs to the technical field of energy-saving lighting. Background technique [0002] Formaldehyde is a poisonous gas, which widely exists in home decoration materials and endangers people's health, so the monitoring of formaldehyde is particularly important. With the development of technology, the monitoring of formaldehyde is mainly developed in the direction of real-time response, simplified operation, low power consumption and low cost. At present, some people in China have made instruments for formaldehyde monitoring. They all use foreign electrochemical sensors, but the cost is relatively high, and they can only display in real time, and cannot remotely notify users in a timely manner. Contents of the invention [0003] The purpose of the present invention is to overcome the problems that the existing aldehyde monitoring instrument has high cost and cannot notify users remotely ...
