Product Usage Instructions

Maintenance
Ensure to replace the batteries when low to maintain accurate measurements. Clean the probe regularly for optimal performance.

Product overview
Soil sensor. Please kindly read the manual before using the sensor, as it can help you with perfect functions and services. The soil sensor is designed with aprobee, which is made of austenitic 304 stainless steel, which has the features of good corrosion resistance and toughness. The mobile APP can view real-time moisture data, and can work with our smart garden timer to realise automatic intelligent irrigation.

Product features

1. Monitor real-time soil moisture and temperature
2. Mobile APP to view the historical record curve
3. Linkage with our smart garden timer to realise automatic irrigation
4. Powered by three AA batteries, with low power consumption and strong battery life
5. Using the highly sensitive probe, fast response, stable and reliable, and accurate measurement
6. Quick plug in and easy to measure

Application scenes
This product is suitable for use in a wide range of horticultural settings, accurately meeting the soil temperature and humidity monitoring needs of all types of planting sites, and can be used to care for a wide range of plants and flowers. Examples include farmland growth, greenhouse planting, orchards and nurseries, gardens and lawns, potted plants, and home gardening.

Add devices to the App

1. Press the button for 5 seconds on the soil sensor, switch to connecting status (WIFI at 2.4Ghz)
2. Confirm that the sensor is in pairing mode (indicator light flashing)
3. Enter the Add Device interface and click “Add”.
4. When the sensor is loaded, click “Finish” on the button, that the addition was successful

Product Notes

1. Install the sensor, please insert the probe vertically into the soil
2. The probe should be in full contact with the soil and compacted to ensure the accuracy of the data.
3. The soil sensor only tests soil and mud, and does not apply to flour, prickly pear, organic crumbs, liquid particles, etc.
4. When the soil sensor is installed, please try to place the probe into the soil as a whole. 5、The depth and tightness of the probe in the soil will directly affect the value and lead to errors. In order to improve the accuracy, please use the method of multi-point testing to obtain the average value.
5. When using, be careful not to touch the stone, and do not use too much force to push the probe, otherwise, the probe will be easily damaged.
6. After the measurement, the probe must be cleaned with paper or a cloth in time.
7. When the sensor is not in use and stored, do not rub or scratch the probe directly with your hands, keep it clean and dry, and away from magnetic objects and other metal objects.
8. Please follow the waste battery recycling process for battery recycling to avoid environmental pollution.

Test Considerations

1. How much moisture is the best? The dry, sandy and fertile soil is not good for accurate data. In the dry or fertile soil, splash some water around the sensor and wait for half an hour to test. 40%-70% moisture is the best.
2. Different data for each test： The depth, density, humidity and other values in each layer of soil are different, and they will directly affect the data accuracy. It is necessary to perform multiple measurements at different locations and take the average value. When measuring, it needs to be at the same level of depth, and the soil around the probe must be evenly distributed and fully compacted and in close contact with the probe surface. Before each remeasurement, thoroughly clean the probe with a paper or abrasive cloth.
3. The actual wireless communication distance and actual usage are affected by the installation spot of the WIFI router: indoor ≤ 10 metres, outdoor ≤ 20 metres.
