Wireless Soil Moisture Meter with Thermometer for indoor and outdoor use


How to use the wireless moisture sensor which monitors water needs

This tool fits well in any office or home to control water needs of your plants

Install two LR6 AA alkaline batteries in the receiver (base station) and don't touch any key ! Then install two LR3 AA alkaline batteries in the sensor, the blue LED light will show for about 20 seconds. If the base station displays moisture level and temperature, the matching process is finished. However, the readings might not be accurate yet because this process takes at least 6 minutes. Now you're ready to insert the sensor in the soil where you want to monitor soil moisture. Start watering your plant and after about 4 - 20 minutes the receiver will show 99%. When the moisture level drops, the receiver will show a lower percentage. Generally spoken an average plant will need water when the percentage drops below 50%. Of course there are exceptions to this rule, dependent on the type of plant. If you want to put the sensor in a different location, take out the batteries first and wait for 5 seconds before you put them back to reset the self learning process of the sensor.

General instructions

  • The depth of the probe of the sensor should be around 8 -10 cm

  • Make sure the probe of the sensor is in plain soil without any obstacles like roots and that the soil is tight around the probe of the sensor, otherwise the readings might be less accurate

  • Leave the sensor in the soil when you water your plant

  • Don’t push too hard, this might damage the probe and/or the sensor

  • Don’t submerge the sensor in water. The sensor is water resistant, but not waterproof

  • Clean the probe of the sensor only with a soft, damp cloth and don’t use any solvents

  • The wireless radio signal has a range of 100 meters in free open air without any obstacles. The actual transmission range will vary

  • If you mistrust the readings, remove the sensor and take out the batteries for 5 seconds before putting them back. Insert the probe again (not in the same spot) and wait for maximum 20 minutes to see if the readings improve.
