Contact Water/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 sensor has a DIP switch. The DIP switch controls the output voltage (high level) of the signal terminal (green line). When the DIP switch is dialed to 5V, the high level is 5V. When the DIP switch is dialed At 3V, the high level is 3.3V.
Compatible with Arduino motherboard and Raspberry Pi motherboard. for Automatic Irrigation Systems, Aquariums, Plants, in The Garden, in Agriculture etc.

【Automatic Function】The float valve automatically refills your water tank, water tower, livestock, animal waterer when the water level drops below the valve level. It automatically stops filling water once it reaches the valve, so it closes when the water reaches the internal float.
【Easy to Install】This is a mini float valve, it is small in size so it is easy to install, the outer thread is 1/2" and 3/4", we used BSP pipe threads, and the outer thread is longer, which is perfect for most BSP threaded connections. If your pipe thread is NPT, you can just add some PTFE tape to the outer thread and it will work perfectly.
【No Electricity Required】The internal float valve allows water to flow until it reaches a certain level. Once the water reaches this level, the float valve is pushed up by the water due to buoyancy, and stops the water flow. When the water level starts to drop, the valve will open again and the water will start flowing again, so no electricity is required.
【Widely Used】It is used by people to maintain the water level of garden waterfalls, courtyard fountains, rain gutter garden projects, use it to automatically close swimming pools, chicken coops, automatic chicken waterers, cattle watering droughts, outdoor rainwater collection barrels, etc.
【Working Water Pressure】The working water pressure of the float valve is 10psi to 150psi. If the water pressure is too low or too high, the float valve will not be suitable for use and will not work or be damaged. Working temperature: 0°C~100°C.
【Easy to Maintain】The float valve is equipped with a filter that can automatically filter sand and stones and will not clog the faucet.
