Timeout waiting for start signal low pulse. It is everything related with the DHT11 or 22.Įxample of output from one of this libraries: Max clock cycles: 16000 Of course, those devices work in the basic Blink example, can use the Serial, led+resistor in breadboard, etc. it always fails.Įven my 'own' library as a experiment, modifying times, delays, quering methods (more polling), different advices found on the Web, reading issues in the GitHub libraries, etc. dht11 simulation with arduino in proteus dht11 proteus library downloaddht11 simulation in proteus more details visit our web site.

It does not matter the board, the component, the model (11 or 22), the pin connected (I even tried to change the V-Data pins), changing the max timeout, the library. I am tired of trying every possible combination. The sensor provides fully calibrated digital outputs for the two measurements. Proteus 8.16 is a major point release featuring a new Push and Shove manual routing mode. It can measure temperature from 0-50 C with an accuracy of 2C and relative humidity ranging from 20-90 with an accuracy of 5.

dht11: by George Hadjikyriacou (0.4.1). DHT11 sensor comes in a single row 4-pin package and operates from 3.3to 5.5V power supply.

SimpleDHT: by winlin (2016), using SimpleDHT.

arduino-DHT-master: by Mark Ruys (2013), using DHT. DHT11 is a low-cost digital sensor for sensing temperature and humidity.

DHT-sensor-library-1.3.0 + Adafruit_Sensor-1.0.2: by Adafruit Industries, using DHT and DHT_U.

2 official Arduino UNO r3 + 1 Funduino Uno.

Furthermore, there is an IC on the back side of the sensor.

1 breadboard (I tried with and without breadboard). The DHT11/ DHT22 consist of a humidity sensing component and a NTC temperature sensor (or thermistor).

Tests: all the combination from the below: After three days trying in many ways how to use correctly the DHT11 with no luck, I open a new post. All these sensors are almost the same except for the difference in flow rate range, operating voltage range, length, size, and material used.
