Problems solved by technology

[0002] Existing water quality detectors mainly involve two types: one is cheap, easy to use, but has few detection parameters and poor accuracy, and generally cannot transmit data to other control systems for long-term online monitoring, or monitor water quality conditions. Secondary analysis; another type of more professional testing equipment, with good long-term operation stability, comprehensive and accurate data, and also supports testing data output, but high cost, large size, and complicated use, making it difficult to promote in non-professional fields

Embodiment 1

[0029] Such as figure 1 As shown, the present embodiment is a water quality detector based on open source hardware, including a core circuit board 10 and an expansion module 20, wherein the core circuit board 10 is provided with a processing unit 11, and the expansion module 20 is provided with a TDS measurement circuit 21, PH measurement circuit 22 , display output unit 23 , communication output unit 24 , sound output unit 25 and power supply unit 26 . The hardware interface between the core circuit board 10 and the expansion module 20 realizes the communication between the processing unit 10 and the TDS measurement circuit 21, the pH measurement circuit 22, the display output unit 23, the communication output unit 24, the sound output unit 25, and the temperature control circuit 41. Circuit connection, the power supply unit 26 provides power for each component in this embodiment. In this embodiment, the TDS measurement circuit 21 is used to detect the total amount of dissol...

Embodiment 2

[0042] This embodiment is a water quality detector based on open source hardware. The difference between this embodiment and Embodiment 1 and its various specific embodiments is that it does not distinguish between the core circuit board and the expansion module, the processing unit and the TDS measurement circuit and the PH measurement circuit. , the display output unit, the communication output unit and the sound output unit are arranged on the same circuit board. Preferably, the peripheral circuit wiring of the processing unit uses a circuit layout disclosed by open source hardware.

Embodiment 3

[0044] The difference between this embodiment and Embodiment 1 and Embodiment 2 is that the body of the water quality detector is separated from the sample cavity, and the probe and electrodes in the sample cavity are respectively connected to the TDS measurement circuit and the PH measurement circuit through flexible cables, so that the sample cavity It is fixed at a suitable collection position and is not limited to the installation position of the water quality detector body. In some specific embodiments, the body of the water quality detector includes the core circuit board and the expansion module in the first embodiment, or, as in the second embodiment, the core circuit board and the expansion module are not distinguished.

Abstract

The invention discloses a water quality detector based on open source hardware, and relates to the technical field of detection. The water quality detector comprises a processing unit, and a TDS measuring circuit, a PH measurement circuit and an output unit which are connected to the processing unit, wherein the TDS measurement circuit comprises a probe; and the PH detection circuit comprises an electrode. The processing core uses the open source hardware, and under a condition of uniform interface, the overall measuring speed, precision, stability, communication reliability and the like can be realized along with the upgrade of the open source software by replacing the processing core mode, and the overall manufacturing cost is reduced by reducing the cost of product testing. The water quality detector is low in price, practical, convenient and higher in measurement precision, and can be applied to the water quality detection of the fields such as domestic water, food processing, chemical enterprises, swimming pools, environment monitoring, water culture and the like, especially to the non-professional fields.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a device for detecting water quality. Background technique [0002] Existing water quality detectors mainly involve two types: one type is cheap, easy to use, but has few detection parameters and poor accuracy, and generally cannot transmit data to other control systems for long-term online monitoring, or monitor water quality conditions. Secondary analysis; another type of more professional testing equipment has good long-term operation stability, comprehensive and accurate data, and supports testing data output, but it is expensive, bulky, and complicated to use, making it difficult to promote in non-professional fields. Contents of the invention [0003] The object of the present invention is to provide a cheap, practical and convenient water quality detector with high measurement accuracy, which can be applied to water quality detection in domestic water, food processing,...
