Soil Humidity Sensor Module 12V Kit
Overview
This sensor switches your garden irrigation pump or the magnetic valve on when the soil is dry and switches off when there is enough humidity in the soil. The measuring head has to be buried into the ground at the depth where it shall measure and has to be connected with the basic device via a cable. Approx. 2 m of cable are included, the sensor cable may be increased up to 20 m with normal 2-pole cable. The device is operated by means of a commercial plug power supply (12 Vdc stabilized, > 130 mA, jack plug 3.5 mm). If the garden is to be irrigated at certain times of the day or weekdays only, then insert timer before the plug power supply and program it accordingly. The soil humidity sensor starts to operate when it receives current from the power supply. Operation sequence:The soil humidity is measured after switching on the operating voltage. The connected pump is switched on for 18...30 minutes if the soil is too dry.If the soil is humid enough the device switches to "Pause" for about 18...30 minutes and makes a new measurement after that. This continues as infinite loop until the operating voltage is switched off.

Good product
Color: Black, Size: Medium
It is as described, looks neat and tidy on the sink. Just big enough to do what I need it to do. My sink stays dry because the wate goes back int the sink.

It is almost great.
Color: Black, Size: Medium
It is a nice sponge holder but the tray is not wide enough and it falls. Because it was the only one I found with a spout, I am keeping it, and figured a way to stick it so the tray doesn't fall. The other thing is that the tray is not sunken enough in the middle for all the water to be routed there, and the spout doesn't always get rid of all the water inside, so once in a few days, I have to manually press it down and more water comes out.
The dishcloth rack is not great for cloths, they get wet.
Other than that, it looks very nice, it is aesthetic, big enough for all my kitchen stuff, and makes my kitchen neater, so I like it.

Love this product very convenient
Color: Silver, Size: Medium
This was great to keep all my brushes, cloth, detergent and scrubby together and neat. I love the drainage and it looks clean. The only thing I don't care for is the bar that holds the cloth comes off all the time. Other than that it is great.
