Contact Multi-point Photoelectric Liquid Level Sensor SKU: CQRSENYW003
Description
Contact Multi-point Liquid Level Sensor, This is a photoelectric water liquid level sensor that is operates using optical principles. Open collector output mode, suitable for connecting various circuits and product applications.
The sensor has no mechanical parts, requires no additional adjustment, and has high sensitivity, low power consumption, corrosion resistance, high pressure resistance, high temperature resistance and chemical stability.
This sensor probe is small in size and has a structure that can be placed up, down, laterally, and diagonally in multiple orientations to detect solution spillage, dryness and horizontal level. 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, high reliability and ultra-low standby power consumption.
Compatible with Arduino motherboard and Raspberry Pi motherboard. for Automatic Irrigation Systems, Aquariums, Plants, in The Garden, in Agriculture etc.
Note: Avoid placing the sensor near bright lights or in direct sunlight as these can cause interference.
