Abstract: A particle sensing device, configured to detect a particulate concentration in a fluid, includes a detecting channel, a sensing space, a light source and a sensor. The detecting channel is configured for the fluid to flow therethrough. The sensing space is located on one side of the detecting channel and connected to the detecting channel, and the sensing space is surrounded by a surrounding wall. The light source and the sensing space are located on opposite sides of the detecting channel, and the light source is configured to emit light towards the detecting channel. The light is configured to hit at least one particle in the fluid. The sensor is disposed on an inner surface of the surrounding wall, and the sensor is configured to detect a scattered light energy generated when the light hits the particle. The sensor is a distance apart from the detecting channel.

Abstract: A water quality detection device including a detection tank, a sensor, the cleaner and a processor is provided. The sensor is disposed on the detection tank and is configured to sense a to-be-detected liquid within the detection tank. The cleaner is configured to clean the sensor. The processor is electrically connected to the sensor and the cleaner and is configured to: execute an initialization procedure, which includes driving the sensor to sense the to-be-detected liquid to obtain a number of initial sensing values and calculating a threshold value according to the initial sensing values; drive the sensor to sense the to-be-detected liquid to obtain a sensing value of the to-be-detected liquid, and determine whether the sensing value of the to-be-detected liquid reaches the threshold value; drive the cleaner to operate when the sensing value of the to-be-detected liquid reaches the threshold value.
