fody weather station, wind sensor
-
I have now opened the outdoor unit.
Anyone that have a code for collection data from 8 IR receivers?
I need to find out what voltage the IR emitter is using, so I don't burn it.
EDIT: google says 1,4-1,6 volt
For wind it is simple to use interrupt
Temperature and Humidity I don't know what kind of sensor it is, that one I can easily change to e.g. si7021/SHT21For wind direction it is using IR.
wheel to control where IR is pointing
For wind speed it is reed switch
Control board
Temperature and Humidity, about 2 cm high

@flopp the Ir 'emitter' is probably a led so you need a current of a few milli amps. Start low (1 kOhm in series) and find out when it starts to function.

It was a HT-01D sensor for measuring temp/hum. It is I2C and address is 0x28.
I found code for HYT 221 that worked fine.

For anyone interested, I am in the process of designing a fully 3D printable weather station. The plan for the 3D printable parts will be:
- rain gauge
- combined wind speed and wind direction sensors
- radiation shield that will house sensors for temp, humidity, barometric pressure and possibly a lux sensor.
- central brain box for holding the MySensors electronics to control everything.
I am just finishing the wind speed and direction sensor parts today. I will post pics later. I have a post in this category for the rain gauge that will be part of the station. I am designing all the parts myself. I still need to figure out a few more parts plus the MySensors electronics and code. I'll post everything as I get the different parts done.

@flopp are you still using old library version? Are you going to make it a battery powered node or else? I noticed you didn't use any sleep in the code

Yes, this is for 1.5

This is powered from a PC, not battery. I want data very often that's why it is not battery powered. I can also change the code if something is wrong.

@flopp - any more images? :)

@sundberg84
Can upload some later today.
I found that I have some problem with the NRf, so I need to open it up.
Will upload new code later today, as well. -
I have not verify all the code yet.
Wind direction is correct.
Temp is little bit higher then another temp that I have on shadow so maybe the radiation shield is not working 100%
Hum: my other sensor that I have outdoor broke a few weeks ago, so nothing to compare with
Wind Speed: I want to verify with an RPM tool. I get some extra indication from reeed switch.
Every second indication is below 1000 micros which is 1 millisecond, which is 1000m/s
Rain: lucky or unlucky I have not had any rain when the mast was up and running -
@gohan said in fody weather station, wind sensor:
Maybe you need a better heat shield, did you try some aluminum foil?
Good idea :)
Should I have the foil inside the shield or outside?
Any pics if you done it yourself?
I think I need some air through the shield so it can cool down. -
I haven't done anything yet, I'm just trying to apply some cheap physics 😀
I'd start from the outside and see what happens
