Humidity Sensor on an Arduino. The DHT1. 1 humidity and temperature sensor makes it really easy to add humidity and temperature data to your DIY electronics projects. Its perfect for remote weather stations, home environmental control systems, and farm or garden monitoring systems. In this tutorial, Ill first go into a little background about humidity, then Ill explain how the DHT1. After that, Ill show you how to connect the DHT1. Arduino and give you some example code so you can use the DHT1. BONUS I made a quick start guide for this tutorial that you can download and go back to later if you cant set this up right now. It covers all of the steps, diagrams, and code you need to get started. Here are the ranges and accuracy of the DHT1. Humidity Range 2. RHHumidity Accuracy 5 RHTemperature Range 0 5. CTemperature Accuracy 2 COperating Voltage 3. V to 5. 5. VThe DHT1. Datasheet DHT1. 1 Datasheet. What is Relative HumidityThe DHT1. Relative humidity is the amount of water vapor in air vs. At the saturation point, water vapor starts to condense and accumulate on surfaces forming dew. The saturation point changes with air temperature. Cold air can hold less water vapor before it becomes saturated, and hot air can hold more water vapor before it becomes saturated. The formula to calculate relative humidity is Relative humidity is expressed as a percentage. At 1. 00 RH, condensation occurs, and at 0 RH, the air is completely dry. How the DHT1. 1 Measures Humidity and Temperature. The DHT1. 1 detects water vapor by measuring the electrical resistance between two electrodes. The humidity sensing component is a moisture holding substrate with electrodes applied to the surface. When water vapor is absorbed by the substrate, ions are released by the substrate which increases the conductivity between the electrodes. The change in resistance between the two electrodes is proportional to the relative humidity. Higher relative humidity decreases the resistance between the electrodes, while lower relative humidity increases the resistance between the electrodes. The DHT1. 1 measures temperature with a surface mounted NTC temperature sensor thermistor built into the unit. To learn more about how thermistors work and how to use them on the Arduino, check out our Arduino Thermistor Temperature Sensor Tutorial. With the plastic housing removed, you can see the electrodes applied to the substrate An IC mounted on the back of the unit converts the resistance measurement to relative humidity. It also stores the calibration coefficients, and controls the data signal transmission between the DHT1. Arduino The DHT1. Arduino. Power comes from separate 5. V and ground wires. A 1. 0K Ohm pull up resistor is needed between the signal line and 5. V line to make sure the signal level stays high by default see the datasheet for more info. There are two different versions of the DHT1. One type has four pins, and the other type has three pins and is mounted to a small PCB. The PCB mounted version is nice because it includes a surface mounted 1. K Ohm pull up resistor for the signal line. Here are the pin outs for both versions How to Set Up the DHT1. Arduino. Wiring the DHT1. Arduino is really easy, but the connections are different depending on which type you have. Connecting a Three Pin DHT1. Connecting a Four Pin DHT1. R1 1. 0K Ohm pull up resistor. Display Humidity and Temperature on the Serial Monitor. Before you can use the DHT1. Arduino, youll need to install the DHTLib library. It has all the functions needed to get the humidity and temperature readings from the sensor. Its easy to install, just download the DHTLib. Arduino IDE. Then go to Sketch Include Library Add. ZIP Library and select the DHTLib. DHTLib. After its installed, upload this example program to the Arduino and open the serial monitor include lt dht. DHT1. 1PIN 7. Serial. DHT. read. 11DHT1. PIN. Serial. printTemperature. Serial. printlnDHT. Serial. printHumidity. Serial. printlnDHT. You should see the humidity and temperature readings displayed at one second intervals. If you dont want to use pin 7 for the data signal, you can change the pin number in line 5 where it says define DHT1. PIN 7. Display Humidity and Temperature on an LCDA nice way to display the humidity and temperature readings is on a 1. X2 LCD. To do this, first follow our tutorial on How to Set Up an LCD Display on an Arduino, then upload this code to the Arduino include lt dht. Liquid. Crystal. h. Liquid. Crystal lcd1. DHT1. 1PIN 7. lcd.
