How do you code a soil moisture sensor Arduino?
The connections for connecting the soil moisture sensor FC-28 to the Arduino in digital mode are as follows.
- VCC of FC-28 to 5V of Arduino.
- GND of FC-28 to GND of Arduino.
- D0 of FC-28 to pin 12 of Arduino.
- LED positive to pin 13 of Arduino.
- LED negative to GND of Arduino.
What is a hygrometer Arduino?
July 17, 2017. This Arduino thermometer and hygrometer takes temperature and humidity readings and displays the data on an OLED screen.
How does Arduino measure soil moisture?
Soil Moisture Sensor Arduino Code Connect the wires from the other (4-pin) side of the amplifier to an Arduino board. The VCC goes to 5V, GND to ground, A0 to an analog pin, and D0 to a digital Arduino pin. You can then run code found here to get it to output the sensor value via the serial port.
How do you build a humidity meter?
To make a hair hygrometer you will need 2-3 pieces of hair at least 12 inches long, a 9 inch by 4 inch wooden block or piece of cardboard, two pins or nails, rubbing alcohol, a dime, tape, a marker, a sheet of plastic transparency, a ruler, scissors, and a hair dryer.

What is FC 28 soil moisture sensor?
FC-28 Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straight forward to use. The two large exposed pads function as probes for the sensor, together acting as a variable resistor.
How do you use a soil hygrometer?
Place the sensor, located in the tip of the Moisture Meter, into the soil. If the plants are in a shallow planter, try to place the tip two thirds of the way down. Same if the plant is in a small pot. For deep pots, plants in landscape beds or lawn areas, push the sensor down into the soil as far as possible.
How can I tell the humidity without a hygrometer?
If you don’t have a hygrometer and are concerned about your humidity levels, here are some ways to do it without the device.
- The Ice Cube Method. The ice cube method is simple and will give you a basic idea of your indoor humidity levels.
- Difference Between Wet and Dry Bulb Thermometer Temperatures.
Can I make hygrometer?
Making a Wet/Dry Hygrometer. Gather the necessary materials. To construct this hygrometer, you will need two thermometers, some cotton gauze, a rubber band, a small container, some water, and a piece of cardboard large enough to hang the two thermometers. Cover one thermometer with wet gauze.
How is hygrometer made?
The temperature of the metal at which condensation begins is the dew point. The psychrometer (q.v.) is a hygrometer that utilizes two thermometers—one wet-bulb and one dry-bulb—to determine humidity through evaporation. A wetted cloth wraps the wet-bulb thermometer at its enlarged end.
