Which sensor is DHT22?
The dht22 ( rht03 ) is a basic, 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).
What kind of sensor is DHT11?
digital temperature and humidity sensor
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).
How accurate is DHT11 sensor?
Its temperature measuring range is from -40°C to +125°C with +-0.5 degrees accuracy, while the DHT11 temperature range is from 0°C to 50°C with +-2 degrees accuracy.
Is the STM32 compatible with the nucleo-f401re?
NUCLEO-F401RE. The STM32 Nucleo-64 boards provide an affordable and flexible way for users to try out new concepts and build prototypes with the STM32 microcontrollers, choosing from various combinations of performance, power consumption and features. For the compatible boards, the SMPS significantly reduces power consumption in Run mode. The…
Do you need probe for STM32 nucleo-64 board?
The STM32 Nucleo-64 board does not require any separate probe as it integrates the ST-LINK debugger/programmer. The STM32 Nucleo-64 board comes with the STM32 comprehensive free software libraries and examples available with the STM32Cube MCU Package.
What does it mean when your DHT sensor says ” failed to read “?
If you get an error message in your serial Monitor while reading the temperature and humidity from the DHT11, DHT22, AM2302 or AM2301 sensor, follow the next steps to see if you can make it work. If your DHT11 / DHT22 sensor returns the error message “Failed to read from DHT sensor!” or the DHT readings return “Nan”:
