This kit measures the current moisture content of the soil, preventing over- and under-watering. The circuit board, shaped like a panda, is equipped with gold-plated contact tips or probes for measuring moisture levels. After simple assembly, you insert the device into the soil of the desired plant. The bright eyes (RGB LEDs) light up every 30 seconds to determine the current moisture content of the soil. The device indicates whether the soil is too wet, too dry, or adequately moist. Warning: Provide your plants with optimal environmental conditions and ensure that the eyes do not turn red! The two rotary knobs allow you to adjust the range and sensitivity. Use the right knob to set the range, and the left knob to adjust the sensitivity. With our panda moisture meter, your plant will never receive too much or too little water again. The kit operates on two CR2032 batteries, which last about two months. It is very important to start with the correct moisture level! The panda features two knobs, one for adjusting sensitivity and another for setting the range (depending on the plant). With the sensitivity adjustment knob, you can select the perfect moisture level from 0 to 100. The range adjustment knob allows you to set the desired range. For example, on a scale of one to one hundred, 80 is ideal. With a moisture content between 70 and 90, you will also avoid overwatering the plant.
