Soil pH Meter Smart Soil Moisture Meter with App Control Digital Soil Test Kit for Plants pH Sunlight Intensity Fertility pH EC Salt Soil Thermometer Humidity Moisture Meter for Garden Lawn Farming

My phone would not allow the app.... but it was no fault of the seller or product. Seller returned my money, thank you!

Good, requires a lot of info

Comes calibrated but also with the option to recalibrate if needed. Batteries included too! Durable compared to other gauges.

Don’t waste your time or money on this garbage! It wouldn’t even connect to the phone. That’s the only way you can use it. Wish I would’ve read the reviews before I ordered. Buy something else… ANYTHING ELSE!

I followed the instructions for the digital soil tester. I downloaded the app, turned on Bluetooth on my iPhone 15 Pro Max, opened the app and it immediately connected. I noticed in the app store that the app got bad reviews, frequently citing bad Bluetooth connection, and losing Bluetooth connection the minute another app was used. I had none of those problems and in fact, I tried to get it to disconnect by using other apps, etc. It stayed connected. It quickly gave me moisture pH and salt readings for some pots where I’m growing herbs. All seemed accurate. One whole side of the plasticized instructions is devoted to calibrating for pH levels. Interestingly, the directions contradict themselves. See my photo. One one page says the device is calibrated from the factory and doesn’t need to be calibrated before use, while the other side says, while it was calibrated at the factory, it needs to recalibrated before first use. Go figure. The device uses 4 AAA which are provided. Easy access to the batter compartment. The apps data is easily read. The values are big, the display is easy to read. There are a number of other data points; See photo. I will use this for determining when it’s time to fertilize my pots, and to check on the salt and pH levels. It was accurate with respect to temperature, moisture and brightness and very easy to set up. Just do everything in the order that is listed. Overall, this is a handy tool and easily connected to my phone. The data it provides will prove valuable over time as I am able to save all the readings for historical reference. Overall, recommended.

This soil monitor measures every important parameter. The best part is that it works quickly while maintaining good repeatability. It is easy to use and pairing with my phone was also easy. After this initial setup, I only have to turn the unit on and open the app, and the readings are automatically updated. There is an LED that indicates when power is on but otherwise does not have any display. I understand that adding a display would add cost and complexity but think it would be better to not have to rely on using another device to get readings.

Great after tilling the soil, treating with fertilizer along with watering and fattening the soil just before planting seedlings, this helps to check the quality and readiness of the soil. It really is better than just guessing or trying your luck without actually having a tester. I only wish it had a rechargeable battery instead of using disposable batteries for the high price. It promotes soil testing and effective gardening, yet it also promotes landfill and earth's toxic trash by utilizing disposable batteries.

This device provides insight into a wide variety of environmental conditions that would be of interest to gardeners. The list of features includes pH measurement, electrical conductivity, environmental humidity, salinity, and soil fertility. I tested this on a tomato plant growing in a pot on my deck, and the device returned good numbers. This is a 'blind' instrument, meaning that it has no display of its own, but depends on a Bluetooth connection with either an Android phone or an iPhone (QR patterns are provided to link to the app store for each phone variety). After a brief procedure, the device paired easily with my iPhone. One thing I normally look for, in electronic devices imported from China, is the quality of the provided documentation or instruction manual. In this instance, the provided support is superb, and consists of a glossy multi-fold with all the information you would need to know about how to use this device. I have reviewed other devices from this manufacturer, and they do a great job in this respect. The pH measurement feature can be calibrated, and like in other instruments from this manufacturer, they include three packets of calibration powder, along with a detailed procedure for calibrating pH. The packets of powder can be dissolved in distilled water to create three reference solutions with a pH of 4.0, 7.0, and 10.01, thereby providing for a precise three point calibration. I have no means of testing whether the other functions of this device are accurate, aside from the ambient temperature and humidity readings, which correspond closely with another weather instrument I use. Serious amateur gardeners will find this device both useful, as well as (hopefully) reassuring about the conditions in their garden.
