Embodiment Construction

[0017] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 , 2 As shown: a color-changing formaldehyde tester includes a housing 1, and the housing 1 is provided with a formaldehyde sensor, a signal conditioner, a microprocessor and an RGB LED lamp, wherein the formaldehyde sensor is connected to the signal conditioner, and the microprocessor is respectively Connect the signal conditioner and the RGB LED light, specifically the RGB LED light is connected to the microprocessor through the driving circuit. The improvement of the present invention lies in that the display area 3 and the discoloration area 4 of the formaldehyde content are provided on the housing 1 , and the display area 3 and the discoloration area 4 correspond to the positions of the RGB LED lights in the housing 1 .

[0019] The display area shows the real-time value of the formaldehyde content in the use envi...

Abstract

The invention relates to a color changing formaldehyde tester and a formaldehyde concentration determination method. The color changing formaldehyde tester is characterized by comprising a casing, wherein a formaldehyde sensor, a signal conditioner, a microprocessor and a red, green, blue light-emitting diode (RGBLED) lamp are arranged in the casing, the formaldehyde sensor is connected with the signal conditioner, and the microprocessor is respectively connected with the signal conditioner and the RGBLED lamp. A formaldehyde content display area and a color changing area are arranged on the casing. The color changing formaldehyde tester has the advantages of being simple in structure and convenient to operate, judging whether formaldehyde content exceeds standard through color changing, accordingly reminding users whether formaldehyde in the use environment harms human bodies in visual, fast and convenient mode, and having good application prospect and market prospect.

Description

technical field [0001] The invention relates to a tester, in particular to a tester which performs color conversion display on the whole or on a certain plane as the formaldehyde concentration in the air changes. Background technique [0002] After people decorate new houses, some decorative materials or paints always leave toxic gases, mainly formaldehyde, and formaldehyde is also more harmful to the human body. Therefore, it is necessary to detect the formaldehyde content of indoor gases, such as Test the new house immediately after finishing, and then test it once a week until the formaldehyde content is safe before moving into the new house. However, the existing formaldehyde degree tester directly displays the formaldehyde content value in the air after the test, and the user needs to compare the formaldehyde content standard in the instruction manual to know whether the formaldehyde exceeds the standard, so the operation is very complicated.
