If you’re trying to read the temperature and humidity from the DHT11, DHT22, AM2302 or AM2301 sensor and you get an error message in your Serial Monitor, follow the next steps to see if you can make your sensor work. Learn how to fix the Failed to read from DHT sensor error. If...
Re: ESP8266 DHT22 "Failed to read from DHT sensor!" #67260By CrossingNevada - Fri Jun 16, 2017 10:15 pm So, will the 8266 recognize "#define DHTPIN D2" if it is coded per se OR do I need to add "#define ESP8266_RAW_PIN_ORDER" at the beginning of the sketch for this to...
var dht = new Dht11(4, gpioController: new GpioController(PinNumberingScheme.Logical, new RaspberryPi3Driver())); var dht = new Dht11(4); In my case both worked the same. I then made some code to read the temperature, this code may need to be called several times until dht.IsLast...

One more query, for now I have to load the code to esp8266 every time i.e esp is getting flashed every time.Is it possible to load once and run it independently ? My expectation is I have connected DHT sensor pin to arduino and arduino is connectedt o esp8266 and every time esp...
If yourDHT11/DHT22sensor returns the error message “Failed to read from DHT sensor!” or the DHT readings return “Nan”: Try one of the next troubleshooting tips. 1. Wiring When you’re building an electronics project, you need to double-check the wiring or pin assignment. After checkin...
