- GitHub - adafruit DHT-sensor-library: Arduino library for DHT11, DHT22 . . .
An Arduino library for the DHT series of low-cost temperature humidity sensors You can find DHT tutorials here Contributions are welcome! Not only you’ll encourage the development of the library, but you’ll also learn how to best use the library and probably some C++ too
- DHT11 basic temperature-humidity sensor - Adafruit Industries
The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed) It's fairly simple to use but requires careful timing to grab data
- DHT11, DHT22 and AM2302 Sensors - Adafruit Learning System
This guide covers the low cost DHT temperature humidity sensors These sensors are very basic and slow, but are great for hobbyists who want to do some basic data logging We'll cover the lower-cost DHT11 as well as the DHT22 and AM2302
- DHT11 with Adafruit. IO: Temp and Hum Monitoring with NodeMCU
By incorporating the DHT11 temperature humidity sensor, we capture real-time data and transmit it to Adafruit io The focus lies on establishing two-way communication between Adafruit io and NodeMCU, providing a practical demonstration of seamless interaction Watch it on YouTube
- DHT11, DHT22 and AM2302 Sensors - Adafruit Industries
We have two versions of the DHT sensor, they look a bit similar and have the same pinout, but have different characteristics Here are the specs: As you can see, the DHT22 (http: adafru it 385) AM2302 (http: adafru it 393) is a little more accurate and good over a slightly larger range
- How to Use DHT11 Humitidy and Temperature Sensor: Examples, Pinouts . . .
Connect the Pins: Connect the VCC pin to the 5V or 3 3V power supply of your microcontroller ; Connect the GND pin to the ground of your microcontroller ; Connect the DATA pin to a digital input pin on your microcontroller Use a 10kΩ pull-up resistor between the DATA pin and VCC to ensure stable communication Install Required Libraries:
- adafruit Adafruit_Sensor: Common sensor library - GitHub
Every compliant sensor can now be read using a single, well-known 'type' (sensors_event_t), and there is a standardized way of interrogating a sensor about its specific capabilities (via sensor_t) An example of reading the TSL2561 light sensor can be seen below:
