Contact multi-point liquid level sensor, working on the optical principle, open collector output mode, suitable for connecting various circuits and product applications.
The sensor has no mechanical parts, does not require additional adjustment, has low power consumption, corrosion resistance, and good chemical stability.
The sensor probe is small in size, and the structure can be placed in multiple directions up and down, horizontally, and diagonally to detect solution overflow, dryness, and horizontal surface. It can be used as a reminder and alarm function.
The multi-point liquid level sensor can detect 4 liquid levels with a detection accuracy of up to ±1 mm and ultra-low standby power consumption.
Compatible with Arduino motherboard and Raspberry Pi motherboard. Used for automatic irrigation systems, aquariums, plants, gardens, agriculture, etc.
