In this video, I'd like to present you cheap Chinese capacitive humidity sensor for Arduino or ESP.
See quick setup with Arduino IDE together with Wemos D1 Lite. It has 3-pin interface and analog output. You can use it as alternative to more expensive Chirp! combo sensor board (see Chirp! here: https://youtu.be/WLyolOGSAXI).
Where to buy:Capacitive soil moisture sensor v1.2Wemos D1 mini Lite.
