This 8-in-1 soil tester reads pH, EC, temperature, humidity, light, moisture, fertility, and salinity, and sends it all to your phone over Bluetooth. It's for gardeners who want a broad read on their soil and a record of how it changes—you can track trends over time and export the data to Excel or email.
One honest note: pH, EC, moisture, and temperature are measured directly, but the fertility figure is estimated from soil conductivity—a directional reference, not a lab nutrient reading. Use it to spot trends ("fertility looks low"), not as an exact number.
A single tool for a broad soil check, with the readings saved on your phone instead of scribbled on paper. If you want one value read precisely, a dedicated meter beats a multi-tool—EC, for instance, is measured directly on our soil EC meter, and pH has its own dedicated meters.
Yieryi comes out of a measurement-instrument factory with 10+ years building pH, EC, and TDS meters. That's also why we tell you which readings are measured and which are estimated—honesty about a tool's limits is the point.
How does it connect to my phone?
Over Bluetooth to the free YINMIK app, available for both iPhone and Android. View live readings, track changes over time, and export to Excel or email.
Does it really measure NPK or fertility precisely?
The fertility reading is estimated from conductivity—a directional reference, not a lab measurement. pH, EC, moisture, and temperature are measured directly.
Does it need batteries?
Yes—it runs on AAA batteries.
Measures: pH, EC, temperature, humidity, light, moisture, fertility, salinity (8 parameters)
pH accuracy: ±0.05 pH
EC accuracy: ±2%
Fertility: Estimated from conductivity (directional)
Connection: Bluetooth to free YINMIK app (iPhone and Android); Excel / email export
Electrodes: High-strength
Power: AAA batteries
How to use it
1. Insert the probe into moist soil at root depth.
2. Open the YINMIK app and connect over Bluetooth.
3. Read the values; treat fertility as a low/medium/high trend, not an exact number.
4. Save or export the data to track how your soil changes over time.
Where it works best
Gardens, greenhouses, fields, and indoor plants—for growers who want a broad soil read plus a record they can revisit.
This soil tester helps you measure electrical conductivity to avoid crop loss from nutrient imbalance. By preventing over-fertilization and soil degradation, it supports sustainable gardening and precision farming. With real-time results, you can ensure the right conditions for healthy roots and consistent yields—solving one of today’s top challenges in modern agriculture.
Excessive soil salinity is one of the biggest barriers to high yields today, but this tester gives you accurate readings to protect plants from salt stress. It’s essential for climate-smart farming, irrigation management, and crop resilience, enabling growers to monitor and adjust conditions before damage occurs. This tool helps overcome the rising issue of salinity in farmlands worldwide.
It tracks soil fertility levels, ensuring plants get the nutrients they need for faster growth. By preventing nutrient deficiency and supporting organic cultivation, helps boost crop productivity and smart agriculture practices. Whether you’re growing vegetables at home or managing large fields, it’s the solution to maintaining fertile, nutrient-rich soil in a changing environment.
It measures 8 key soil factors: pH, EC, temperature, humidity, light, moisture, fertility, and salinity—giving you a full picture of soil health.
The device uses high-precision electrodes with a pH accuracy of ±0.05 and EC accuracy of ±2%. You get reliable, consistent results for better crop decisions.
Yes, simply connect via Bluetooth to the free mobile app. You can view real-time soil data, track changes over time, and even export reports to Excel or email.
Absolutely. It’s designed for greenhouses, gardens, fields, and labs. With durable electrodes and long-lasting battery power, it performs well in different environments.
Yes! Home growers love it for houseplants and gardens, while farmers and greenhouse managers rely on it for precision agriculture and higher yields.
By giving you accurate soil data, it helps you adjust watering, fertilization, and soil management—preventing crop stress and boosting overall plant health and productivity.
