The LED soil moisture sensor helps you know exactly when to water your house plants. Designed to monitor the moisture level at the root zone, it flashes green when the soil is adequately moist and red when it is too dry. It’s a simple way to keep plants healthy and prevent over or under watering.

Soil Moisture Sensor For Indoor Plants

This soil moisture sensor is designed for use in pots and planters. It checks the condition of the soil and gives a clear visual signal through its LED light. Place the probe directly into the soil near the roots, and it will automatically detect when the moisture level drops below the ideal range for your plant. For a full indoor automatic watering system for all your plants see our indoor watering system.

Easy To Use LED Moisture Sensor

Using the moisture sensor is simple. Insert it into the potting mix and let it measure the soil moisture level. A green light means your plant has enough water, while a red light means it’s time to water. The device helps avoid common watering mistakes that can lead to plant stress or root problems.  In addition, our Quadgrow self watering planters can also assist with recycling water and can optimise moisture levels for 14 days.

Soil Moisture Sensor Sizes

The moisture sensor is available in two sizes to suit different pots and planters. The standard size measures 20cm, while the long version measures 30cm. Choose the size that best matches your container depth to reach the active root zone of your plants.

Requires 1 x AAA battery (not included).

How does the soil moisture sensor work?

The sensor measures changes in soil properties that relate to water content. It then uses those readings to estimate how much moisture is present near the roots.

Can this moisture sensor be used outdoors?

It is designed mainly for indoor pots and planters but can be used outdoors in sheltered conditions.

Does the moisture sensor show when the soil is too wet?

The LED will stay green when moisture levels are balanced, helping you prevent both dryness and over watering.

What battery does the soil moisture sensor use?

It requires one AAA battery, which is not included with the sensor.

Where should I place the moisture sensor in the pot?

Place the probe near the plant’s roots to get the most accurate moisture reading.

Is the moisture sensor suitable for all plant types?

Yes, it can be used for most house plants and potted plants that need regular monitoring of their soil moisture levels.

Great Cooling, But Lacking Support
Color: White, Size: Standard
I have to agree with some of the other reviews—this pillow just doesn't offer enough support. It initially feels plush and inviting, but after a minute or so, your head sinks too far and ends up pressing against the underlying latex, which has a rubbery, somewhat uncomfortable feel. It might be an excellent fit for those with smaller frames, but for me, it fell short in terms of proper neck and head support. On the plus side, the cooling aspect is impressive. It's cool to the touch and noticeably more breathable than many pillows I've tried. I've seen some complaints about it not staying cool all night, but honestly, no pillow really does. Casper's claim of "12 hours of cooling" seems like marketing optimism—your body heat will eventually warm up any pillow, no matter how well-designed. That’s just basic thermodynamics. All in all, it's a well-made pillow with excellent cooling performance. If you have a smaller frame, this could be a great choice. Unfortunately, it just didn’t work for my needs.

Is this a joke?
Color: White, Size: King
I don't usually write reviews, but I have to for this pillow. The pillow measures 16" x 32", not 18" x 34" as stated in the description. That's not really a big deal, but they should have the correct size in the description. The problem with this pillow is the total lack of support. My head falls through this pillow within a half hour of laying my head on it. This causes me neck pain and I have to switch to my old pillow in the middle of the night. I'm a bigger dude that's 6'3" and I only sleep on my side. I thought this pillow would be great based on the other reviews that stated it works for side sleepers. I would describe this pillow as a greatly overpriced marshmallow. The pillow does have some decent cooling properties, but they don't last all night as described. This pillow would probably work great for someone who sleeps on their stomach. I wouldn't recommend this pillow to a bigger dude that's a side sleeper. Note: I did find a great Casper pillow that works for me. I bought the Casper Sleep Essential Cooling Foam pillow on Amazon. It's the one that's all foam with a phase change layer to help with cooling. The pillow has great support and it doesn't cause me any neck pain. The best part is the price, it cost less than half the price of the Hybrid Snow Pillow. I hope this review helps someone.

A Near Perfect Pillow
Color: White, Size: King
I was hesitant to order this pillow because it was so expensive. I was looking for a cooling pillow and after a previously purchased pillow lost it's "cool" after a few nights of sleeping on it, I was concerned that this Casper pillow would do the same. The pillow is so comfortable. My only complaint is that it does not seem to hold the coolness all night. I find I need to flip the pillow over part way through the night. But, when I flip the pillow, it is perfectly cool. The pillow is supportive without being too firm. I love this pillow!

Not quite right….
Color: White, Size: Standard
I’m torn on this pillow. While it does have merit, there were some serious “flaws” for me. I am a side sleeper and I’ve been on the hunt for a neck supportive pillow. This didn’t have that for me. The night started with good possibility, but I woke up several hours in and found the pillow flat where I was; all the filling had moved to the top. It IS very cool to the touch and I could definitely tell it was cool while sleeping on it. The loft of this pillow is fine, but not stupendous, and the softness was pretty great. Overall, just not the best. If the filling had stayed put through the night, I might’ve kept, but as it was, I returned.

Does the job!
Color: White, Size: Standard
This pillow offers superb support and stays cool. It replaced my previous one from a couple years back. I did notice that, like so many things, it isn’t as full as my previous one but still offers a good nights rest for this side sleeper.
