Humidity Sensor Circuit Circuit Diagram The DTH11 is a sensor designed to sense the moisture level present in any matter.hobbyist use to implement them into the prototype and make a prototype of it.Usually, the DTH11 consists of four pins out which three are used for the implementation. The pins are accordingly ordered as . VCC pin; Data-out pin; GND pin

Humidity sensor Circuit using Opamp Circuit Diagram
In this project, i wanted a startup animation screen which would display the my Channel name and Project name, next I needed to display the data from DHT11 sensor, so i set the cursor position on my LCD according the convenience and simply dumped the Temperature and Humidity values from the Variables that hold the data from sensor on the LCD screen using lcd.print command and that's pretty
Learn How to Make DIY Weather Station With Arduino and DHT11 Sensor in a Detailed guide along with Arduino Code and Circuit Diagram. Monday, March 17 2025 Breaking News. Colour Sorting Machine Project Arduino and TCS3200 The Arduino Weather Station uses the DHT11 sensor to read the surrounding temperatures and humidity. This sensor is Humidity Sensor: Humidity is the amount of water vapor present in the air. It can be a reliant indication of the likelihood of precipitation. The circuit is very straight forward, as you can see in the picture above. The red wire is supplying the sensor with 3.3 Volts from the Arduino board. The black wire is ground i.e. 0 Volts.
Arduino - Temperature Humidity Sensor Circuit Diagram
Working of Humidity sensor Circuit: In this circuit we are using an Integrated Humidity Sensor HIH-4030, three Op-Amps to sense the output from the sensor and switches the indicator LED's based on its intensity. For showing the results we have 3 LED's. The sensor is very simple and has 3 pins.
In our previous article, I have explained how to interface temperature humidity sensor with arduino and read out displayed on serial monitor of arduino IDE. In this post I have explained how to display the reading on a 16x2 LCD display for the proposed digital temperature/humidity meter using Arduino.
