I gave him a lift to the airport recently and in exchange he gave me a box with electronic stuff, wires, resistors and LEDs. (i.e, either motor turned on / off) Specifications: To power up this sensor you need 2.5V to 5 volts, which is perfect. NodeMCU interfaced with humidity sensor gets the analog input as moisture and post the moisture value to the cloud. Interface single wire DHT11 sensor with NodeMCU and read the value of Temperature and Humidity from DHT11. is in the same network. Soil Moisture Sensor has both digital and analog output. The ESP8266 reads the soil sensor value on analog pin A0. While monitoring the sensor gives us true or false condition with respect to measured moisture content in a soil. Before you begin. The two probes allow the current to pass through the soil and then it gets the resistance value to measure the moisture value. It will send the readings to the ThingSpeak … The ESP8266, DHT11/12, and the Soil Moisture Sensor, as you can see the diagram below there are 3 sensors to accomplish this projects the ESP8266 WiFi Transceiver, two plate soil moisture, and the DHT11 Temperature & Humidity sensor. Water leakage sensor can also be powered with nodemcu output power. If the soil moisture reaches a value (adjustable through the potentiometer on the module), the digital pin (D0) goes high and the D0-LED on the module turns on. So, I decided to try it by myself. The soil moisture sensor consists of two probes which are used to measure the volumetric content of water. This project also tested in ESP8266 12E NodeMCU, ESP8266 Version 7, ESPDuino, WeMos Board. This Moisture Sensor can be used for detecting the moisture of soil or judge if there is water around the sensor, let the plant in your garden able to reach out for human’s help when they are thirsty..
