There was a little trace of greenish powdery substance in the back side of the capacitor across about 3 of the strips that look like capacitive touch pads, inside on the actual sensing component and cleaned it of but the plating is missing on one of the strips. I understand it’s a capacitor type component, my question is the type they use in these are not sealed cans or dipped but two flat layers with an absorbent material in the middle. Yes they are cheap but that defeats the purpose of attending electronics engineering classes if I can’t figure out the issue. I believe it’s pulling/shorting my controller out immediately upon plugging the last wire in and yes I even tried it still powered up because I thought the board was shot until I pulled the wires.
#DHT11 PROTEUS LIBRARY CODE#
Well, perhaps it is but I mean I was setting up to work on my code and I almost want to say I seen a spark come from the 9v battery that comes with some of the kits for the Arduino Uno… Anyway.
#DHT11 PROTEUS LIBRARY SERIAL#
So I’ve got one of the dht11 break out boards with the 10k resistor already integrated and I’m having a difficult time because first and foremost.the data only became true on my serial monitor once I swapped the 5v and GND from what the board shows and any tutorial you might find will tell you… That’s not my issue tho.

Source code is written as “Ready To Use”. If you prefer simple solution, use the GW-USB-05. As receiver, you can use E03-TR example (TR module has to be inserted in CK-USB-0X) and IQRF IDE terminal, or you can use RF-UART conversion source code ( UART_LINK.c) and any serial terminal. This line has to be “pull-uped” – sensor has open colector output.Īttached source code reads data every second. You need only power supply for sensor and one wire for data line. This article describes temperature and humidity measurement with DHT11 sensor connected to TR module.
