Hello. I’ve just made my first plant monitor using Blynk. I’ve installed a soil moisture sensor and I’ve alresdy ordered a small water pump so I can water the plant with Blynk.
I have a question regarding the soil moisture sensor, as I’ve seen there’s quite a few people here using Blynk for simillar projects. The sensor displays 100% percent when not in soil or when it’s in dry soil (i filled a cup with dirt and tested it). I also filled another cup with dirt and put some water in it, the sensor displays ~60%. Are these values correct? Shouldn’t it be the other way around? Like 0% when in dry soil. In the screenshot above the sensor is located in a pot about 20-30 centimeters in size and about 20 cm in diameter that I’ve watered about 3 days ago. Thank you
