In this video, we will talk about how the capacitive liquid level sensor works.
We all love using plants to brighten up our living spaces, but taking care of them is no easy feat.
How to keep these plants alive may cause a headache, especially when we’re away for a holiday.
Well, in that case, drip irrigation may be a good way to solve this problem.
Besides, if we can monitor the water tank and get informed to refill it in a timely manner,
then our dear plants may enjoy their vacation just as we do.
So how do we know if the water tank is nearly empty?

***************************************
This is a non-contact liquid level sensor with a status indicator and adjustable sensitivity. It can be used in liquid detection of non-metallic containers or pipes, suitable for all types of detection of curved or flat surfaces, arcs, cylindrical containers, or piping fluids. The status feedback of the sensor can be given in real-time.
Besides that, the sensor comes with a 4-pin sensor adaptor that can directly collect digital signals, which is convenient for connecting with Arduino or other main controllers. This liquid level sensor can be widely used in liquid detection of a tank, water dispenser, etc.
