Very useful and great value
I use it to detect water in a four inches PVC pipe. If the water does not present then it will trig an alarm. This is to prevent the water pump from over heat. The sensor is very tiny but is very efficient to do this job.

It is very tiny sensor but very useful.
I use these sensors to detect the water in the 4 inches diameter PVC pipes. They are the suction pipes of water pumps for 100 rooms apartment. When there is no water in the pipe, this sensor will trigger a siren or alarm. Someone will go to take care and fix it before the water pump becomes over heat or burnt caused by no water. The sensor is very useful and I don't need to modify any of the pump system because the sensor is non-contact and install outside the pipe. Very smart and good small sensor to detect the water.

Very useful plus one hidden extra function.
My small bed room has only one light with one wall switch. This remote light switch is not only provide to me to remote turn on/off the light from any where in the room and out side the room but also give me to install one more light and one more ceiling fan. So I now have 2 lights and a ceiling fan from only existing one power line. Their are a few nice features in it. The first nice feature is the channel A from the blue line is automatic turn on when ever the power line is connected. I like this feature and it is the "Must Have" for my next buy. Why? because it means whenever I get into the room when I switch the wall switch to "On", I will always have the light in my room without trying to find the remote which may be in the dark. The drawback of this feature is you should to make sure that you turn of the wall switch before leaving the room or the house, otherwise it might turn on automatically when the main power is interrupted.
The second lovely feature is the "D" button on the remote. When press D button on the remote while channel A is on, the light on channel A will blink one time. This is a feature that I can use to control multiple colors or multiple brightness light that uses toggle on/off technique to control its function. The third features is one button and one button off. This feature I can press one "ON" or "OFF" to switch all channels on or off.
Compare to the price and its features and functions which are very useful to me, the money I paid for each is only $4.99 with free shipping to Thailand is nothing to me. Very great value to money at this moment. Only one thing that I will need to prove is for how long it can be function.
