Does this automatically turn on the water, too?

No.

Are extensions available?

Asked by NSGardener April 28, 2016

I'm an Electronics expert but I'm retired. From the looks of the cord I assume you need it longer than 16 feet. It's a 3 conductor cord with an orientation notch on the plug so you might have trouble finding a suitable extension. We had about a third of an inch of rain this morning and I've tucked it under a bush that's about 12 feet away from the main unit. It seemed to work just fine.

If my facet is 400 ft away from garden, is there anyway the moisture sensor will work?

The 3280 will not work with the wired Moisture sensor. It will however work with our item 3300 which is a wireless moisture sensor.

will it work on top of the ground?

Answer

The Moisture Sensor works by measuring the moisture in the soil that is packed against the front of the probe. I cannot be set to stop watering if rain just starts and has not soaked in the ground.

Is it possible to connect 4 of these to the water control - 1 for each zone?

Sensor leaks and once water is inside it stops all programmed water cycles. 1. Water inside sensor when I opened it. 2. No seal around cable entry to housing 3. Nice o-ring seal around knob entry to housing. Melnor dropped the ball on this. Good electronic design using capacitive sensing. If you do buy it, put some silicone around the area where the cable enters the housing and it might work fine for a long time.

Bought this as an add on to the 2 zone Melnor timer. I'm trying to grow grass from seed and ended up turning the moisture sensor off for now. I need to keep the top layer moist to promote the seed to germinate. Once I get the grass to grow in, I'll set it for a soil moisture setting. It is not positioned in one of the watering zones as per the directions, so only rain (and soil moisture) should affect it's control of the timer. I could have waited till the grass grew in, but it's good to have.

There is a simple test. Put the probe in a cup of water and see if the next cycle will run. If it does no start the next cycle remove the probe from the cup and dry it off and in a few minutes the cycle should resume.

The idea is brilliant but not well executed. The connection cord is much too short and only of use in very small garden beds. Even worse is the fact that there is not enough range. I have it set at the wettest position but it keeps the water shut off even when the plants have wilted.

If the antenna symbol remains steady then the Aqua Sentry is sensing the probe. It is important to make sure the soil rock and debris free is packed against the front of the probe. If it is being sensed and you feel that the probe is set properly we can work with you to test the unit and replace it if necessary under its 7 year warranty. Please contact us at info@melnor.com. Please put Ben in the subject line and give me your phone number and let me know when it is convenient for me to call.
