      @suhaila96 Hello I have not seen your question since I reviewed this topics, today. What do you mean about "setup your circuit"? How did you connected you watermark sensor and to what?

      Hi there! Reading the Watermark sensor is no easy task indeed. Took us a while to get accurate and reliable data out of these sensors. First of all, take a look at the official documentation provided by Irrometer: https://www.irrometer.com/200ss.html Especially the pseudo-AC excitation is very important and make sure you calibrate the readings using the soil temperature. There's quite some off-the-shelf hardware on the market already. Look for a device that has a low power consumption so you can measure throughout the year, for example: https://www.crodeon.com/blogs/news/connecting-a-watermark-sensor-to-the-cloud Let me know if you have any more questions!
