Description

This float switch is a device used to sense the level of liquid within a tank,the switch may activate a pump,an indicator,an alarm,or other device. Simple structure,easy installation liquid level controller.Light weight and simple working principle,high reliability. It can be easily converted from normally open to normally close by inverting the float. Please Note: because the current that the switch can carry is much little(0.5A), you must use a relay or contactor when it is connected by a load, relay or contactor are not included here.


Feature

FAQ


Question: Does this work with Arduino?

Answer: Yes it can, with some external components. It just acts like a simple switch. You could connect it to a 3.3V potential on one of its wire and an arduino input on the other wire. You should connect a 10 Kohms pull down resistor between this used input and the ground to force the input to zero when the switch is open.


Question: Can this be used with potable water ? Is it food grade?

Answer: Yes, it is completely sealed in plastic. I see no reason for it not to be safe for potable water. I am using it to monitor RO water levels in a storage tank I drink from.


Question: Can these be used with a gauge to tell how much water is in a tank? How would this sensor know how much water is in the tank?

Answer: No, they are used to determine when water is at a certain level. The float only travels about an inch and the sensor is like an on/off switch. When water is high enough the float moves up and it turns on. You could put more than one in a tank at different levels and determine the amount of water based on.


Question: What is the gauge of the wire? Single or multiple strands?

Answer: I didn’t check the gauge. These are intended for control signals- not high power switching. They work well.
