Among them, water pollution is the most serious problem. At present, factories often dump untreated waste or waste water and other pollutants into rivers and reservoirs. However, these pollutants will pollute irrigation or civil water after being washed and converged by rainwater, which will not only increase the cost of water treatment, but may also cause pollution and harm to humans or aquatic organisms.

Therefore, government agencies or environmental testing companies hired by the government will use portable water quality sensing devices to perform random inspections in the waters discharged by factories to find out whether these factories have random discharge of pollutants.

However, when two types of batteries are used to supply different sensors, the power consumption speed of the two types of batteries is different, so if one of the batteries is insufficient first, the sensor will return an abnormal value (for example: high When the voltage battery is dead, its low voltage battery will continue to drive the sensor for detection, but because the high voltage battery is dead, the motor cannot be driven, so the value detected by a small number of sensors will be An error occurred), resulting in an error in the output test report.

Therefore, how to solve the above-mentioned deficiencies and inconveniences of conventional use is the direction that relevant industries in this industry urgently want to study and improve.

The detector forms a high-voltage stabilized circuit that is electrically connected, and the high-voltage stabilized circuit The other side of the road is electrically connected with a step-down circuit, and then the other side of the step-down circuit is electrically connected with a low-voltage voltage stabilizing circuit that is electrically connected to the first sensor and the second sensor, which acts as a water quality sensing device During detection operation, the power module can step down the high-voltage electric energy into low-voltage electric energy through the step-down circuit, so that the first sensor and the second sensor can be supplied by a single power supply It is used to avoid different power consumption speeds, and can prevent the sensing module from returning wrong detection values, thereby achieving the purpose of improving the accuracy of water quality detection.

In addition, the power supply 131 is electrically connected to detect The power detection module 135 that supplies the remaining power of the power supply 131 and sends out a power-off signal when the power is insufficient.

The second sensor 112 can be a turbidity sensor, a suspended solid sensor or a chlorophyll a sensor, such as a sensor or an oxidation-reduction potential sensor that can be driven by low-voltage electric energy. Sensors that have self-cleaning function and require low-voltage power and high-voltage power to drive.

Furthermore, the power supply 131 of the aforementioned power module 13 can be various types of batteries such as lithium batteries, accumulators, or rechargeable batteries. The power supply 131 can provide the power required by the sensing module 11 and the processing module 12 through the power supply 131.

The power supply 131 of the power module 13 can transmit high-voltage (such as 12 volts) electrical energy to the high-voltage stabilizing circuit 132, so that the high-voltage electrical energy is constantly transmitted to the sensing module 11 through the high-voltage stabilizing circuit 132 The second sensor 112 and the step-down circuit 133 can drive the cleaning brush 1121 of the second sensor 112 to perform a cleaning action. After the step-down circuit 133 receives high-voltage power, it will The electric energy is reduced to low-voltage (such as 3.3 or 5 volts) electric energy, and then the low-voltage electric energy is transmitted to the low-voltage stabilizing circuit 134, so that the low-voltage stabilizing circuit 134 can convert the low-voltage electric energy Constantly transmitted to the sensing module 11 and the processing module 12, so that both the first sensor 111 and the second sensor 112 of the sensing module 11 obtain electric energy and can perform water quality detection operations in the water area, and The processing module 12 obtains power to operate, and during the water quality detection operation, the second sensor 112 can perform cleaning operations through the cleaning brush 1121 to maintain the accuracy of detection.
