Adafruit AHT20 - Temperature & Humidity Sensor Breakout Board - STEMMA QT/Qwiic

Product Information

To learn about more temperature sensor, we have introduced the following sensors in the blog 9 Types of Temperature Sensors You Should Know: The following code will read the measured values from the AHT20 temperature and humidity sensor and print them through the serial port. #include "DFRobot_AHT20.h" This example uses a couple of libraries, both of which can be installed using the library manager. if you search for the AHT20 one first and you are using a newer version of the Arduino IDE it will install the other one as well – which makes things a bit easier.

If the plugin is configured for Sensor model AHT10 and other devices configured in a task use the I2C bus, a warning is displayed (see example below) that combining them with this device may cause issues on the I2C bus, resulting in all I2C devices no longer working as intended. This may occur immediately, or only after some time, like 10 minutes or an hour.So color coded for ease of use, this layout shows a connection to the module ESP8266 and AHT20 layout Code Example Once again for ease of use I connect a Dual Base Shield with a Wemos Mini and then connect the sensor to that as well Name This sensor can be widely used for measuring the environmental temperature and humidity of home electronic equipment, the temperature and humidity of automobiles and so on. Features

note AHT20 can't directly get the temp in F, the temp in F is calculated according to the algorithm: F = C x 1.8 + 32 Documentation is produced by doxygen. Contributions should include documentation for any new code added. retval true If the measurement is completed, call a related function such as get* to obtain the measured data. The AM2301B is a nice but inexpensive temperature and humidity sensor from the same folks that brought us the AM2302.Based on the AM2301B temperature and humidity sensor: users can also customize products according to actual application scenarios and cost considerations by selecting chips, PCB boards, shells, protective covers, wires, etc. The sensor outputs calibrated digital signals in standard IAHT20, as a new generation of temperature and humidity sensors, has established a new standard in size and intelligence. The sensor outputs calibrated digital signals in standard I 2C format. AHT20 is equipped with a newly designed ASIC chip, an improved MEMS semiconductor capacitive humidity sensing element and a standard on-chip temperature sensing element. Supply voltage

Sensor model Selection of the connected type of hardware. (AHT2x sensors have a slightly different intialization.) AHT21 is equipped with a newly designed ASIC dedicated chip, an improved semiconductor capacitive humidity sensor element, and a standard on-chip temperature sensor element. Its performance has been greatly improved or even exceeded the reliability level of the previous generation of sensors, such as AHT20 ( Introducing AHT20 I2C Temperature and Humidity Sensor- Industrial Grade). AHT21 temperature and humidity sensor is able to perform stably in extremely harsh environments more stable. Specifications Comparision of AHT21 and AHT20In fact, this enclosed sensor looks an awful lotlike the popular DHT22/AM2302 temperature and humidity sensors, but unlike classic DHT sensors, it has an I²C interface! That's right, you do not need to use a bit-bang timing-specific protocol to talk to the AM2301B, it uses plain-old-I²C. And, you can power it with anything from 2.5V to 5.5V so it's good with 3V or 5V microcontrollers. Whew, that makes things a little easier, doesn't it? You also need an I2C support library from the same folks for the library above to work and that is available from – https://github.com/adafruit/Adafruit_BusIO
