Yes! It is the same weather station again, but it uses a bigger display. Pls take a look at previous instructables.
I still had this 320X480 lcd display for the arduino mega and i was wondering if i could rewrite my sketch to work on it. I was lucky because of the library HX_8357 created by Bodmer (thanks mate!) is a very good one and can print floats and etc. It took me about an hour and it was working perfect.
Step 1: Parts Needed
- Arduino mega or Mega2560 pro
- 3.2 TFT LCD ILI9481 (HX8357)
- DHT11 or 22
- Analog light sensor
-Libraries and sketch
Step 2: Software
Download sketch and included libraries, compile and upload.
Step 3: Prototype
I did not receive my prototype shield for my Mega that i ordered from china, so i sacrificed my RSD Mega for a time.
But i was careful and used thicker soldering wires and soldered them really carefully.
I did not wanted to change the pinout. So i made a little pcb plate with female headers for the sensors.
Not beautiful at all, but it does the job till it is finished.
I used a BMP180 sensor this time because my BMP280 sensor was acting weird and it was showing inaccurate values.
2019.02.15. Added absolute humidity calculation.
Step 4: Future Plans
I have read many articles about dust and air quality sensors. So i decided to order 2 sensor of 2 different types.
It seems not very hard to interface them with arduino boards and build in this project.
I am planning to add Air Quality readings, pressure in mmHg, digital precision humidity and light intensity.(and who knows what more)
The reason why i posted this instructable is that we have a bigger board, display , huge amount of memory (compared to the Uno) and many analog and digital pins.
When i take a look on the display it is a bit satisfying to read all possible formats of the measurement ; that's why i added those.
I have already bought the plastic enclosure for this weather station. When it will be finished i will upload the results.(i hope)
I hope some of you will have a good use for it.
Thanks for reading this instructable!
