Nice Shamee, very informative video.
Thank you kindly
Is dht 11 sensor required or we can only measure gas value with mq 135 sensor
Dht is required to measure temperature and humidity. If you want to read gas alone you need only mq135.
hi sir it giving nan input for temperature and humidity and 0 for mq135 pls respond
Check the connection and also the pin you connected in esp8266
Field Value unavailable why?
it is giving nan values for temperature and humidity
Something wrong in the connection or there might be some loose connection
Can we use bylnk instead of thinkspeak
Yes. Please watch this video.
ruclips.net/video/imYEL8wqCqk/видео.html
how can i change may port com3 into port com5?
No need to change. port number will differ for each one. You can use your port.
sir why field value unavailable
Check your circuit connection. Sometimes due to traffic the value won't be available. Try after sometime or next day.
Sir , Where can we get this source code
The code which you uploaded
Please check video description.
Sir Thank you ..but while verifying or uploading the code it showing
4 | #include // Including library for dht
| ^~~~~~~
compilation terminated.
exit status 1
Compilation error: DHT.h: No such file or directory
Install the DHT library from Arduino IDE -> Tools -> Library.
@@TechTrendsShameer ok sir done thank u
Bro in coding funa is showing error
Send me the full error message.
1
Code not uploading
What is the error?
Fatal esptoolpy. Error
Here are some possible causes of a fatal esptool.py error:
1. Unused COM ports: Esptool.py can't handle COM-port numbers with double digits.
2. Board not connected to the correct communication port: The board might not be connected to the correct communication port selected in the Arduino IDE.
3. Insufficient power: The 3.3V power supply for the ESP chip needs to supply large amounts of current.
4. Missing bootloader: The ESP8266 SDK uses a small firmware bootloader program.
Here are some possible solutions:
Disconnect all wires
Install an older version of ESP8266
Install a 10uF capacitor between Enable (EN) and GND
Install the CP210X driver
Upload Blink
Change the board to Olimex MOD-WiFi-ESP8266 (-DEV)
Remove all unused COM ports
Uninstall the CH340 driver and install a fresh copy
Download the CH340 driver from sparkfun.com
@@TechTrendsShameer can I choose com3 port for uploading because sometimes com5 port is not showing in ports only com3 and 4 is showing.and sometimes showing com6 port
To identify the correct port, first remove the cable and see what are the ports showing (If there is nothing then its fine). Then connect the cable and see which is the new port showing and connect to that port.
