Dew Point Sensor Arduino

A dew point greater than 20 c 68 f is considered uncomfortable and greater than 22 c 72 f is considered to be extremely humid.

Dew point sensor arduino.

As the air or gas temperature drops its ability to absorb water vapour drops until it becomes completely saturated and below this dew point temperature water droplets will start to form. As such if you re a person who is interested in knowing the current weather conditions you ll probably want to know what the dew point is too. Dew point sensor np330 g. A higher dew point indicates more moisture in the air.

Ends to 5v and ground lcd 3 vo pin to pot wiper lcd 4 rs pin to digital pin d7 lcd 5 rw pin to ground lcd 6 e pin to digital pin d8 lcd 11 d4 pin to digital pin d9. In degrees celsius but seen on the display with a different symbol to avoid confusion with the temperature feature. Protoboard optional 2 assembly. Here is my setup using only one dht11 humidity sensor.

Measuring trace humidity in gases. Further on you can learn about details of relative humidity heat index and dew point the example shown further down shows you how to use the dht22 in your own arduino sketches. The dht11 humidity and temperature sensor make it really easy to add humidity and temperature data to your diy electronics projects. It s perfect for remote weather stations home environmental control systems and farm or garden monitoring systems.

Add tip ask question comment download. Dew point sensor for measuring trace humidity in gases within a measurement range of 80 c dp to 20 c dp. Check humidity temperature and dew point with arduino uno with dht11 sensor through serial monitor. In this tutorial i ll first go into a little background about humidity then i ll explain how the dht11 measures humidity.

Sensor shield for arduino uno optional sensor shield for arduino nano optional wires. The dew point is the lowest temperature that allows water vapour to remain in a gas without condensing to a liquid state. These sensors are relative humidity sensors with a built in temperature sensor which allows the humidity reading to be more accurate see table below for accuracy of the device. Select arduino nano board.
