Now here’s my problem : none of them actually shows correct data. Temperature sensor pretty much always shows the same amount ( 8.2ish ) no matter when I try it out ( and it’s around 25 degrees here ).
Proximity sensor always finds something even tho there’s nothing there ( sometimes it doesn’t find anything but it’s just random ). I’ve tried switching the lights off/on, I’ve tried placing it in darker / lighter areas - still not working.
My collision sensor says it’s always in collision with something, again occasionally printing that it’s not ( but it’s completely random ).
Finally, my accelerometer doesn’t really work at all. It just stand at (0,0,0) no matter what happens.
I hope I’m doing something completely wrong.
I should also mention that I’m working with TightVNC to control raspberry from my PC ( haven’t had any problems with it so far ) and that I can’t seem to connect to my grovePi from my pc ( via “http://dex.local” ). At this point I have no clue what’s going on and why. I’d appriciate some help. If there’s any other info I can give you, just say it. I didn’t bother rechecking if I installed GrovePi correctly because everything seems to be working, it just shows bad info.
Can you add a link to the digital accelerometer and the temperature sensor that you are using. (There are a couple of different sensors for this, just want to make sure that both of us are looking at the same thing)
Can you upload the program that you are using and the output that you get.
Here is a pic from the temperature sensor output http://prntscr.com/aropx7 ( it’s always like that, a no, it’s not 8 here )
The rest of the sensor pretty much show the same thing all time time ( collision just prints 0, axis accel. 0,0,0 ; and proximity is always at the same voltage level no matter the light / distance or anything else )
I attached programs I use and the log you asked for.
First of all I’d like to apologize for the late reply. I had some RL issues and I had to put down my hobbies for some time.
Now back to the problem…i2cdetect sees Accelerometer perfectly ( http://prnt.sc/b3w23e )
Temperature sensor results : http://prnt.sc/b3w1wl
Also looking fine ( it started around 450 and I put it in my hands for about 30 secs and it jumped to 550 then back to 460ish after some time when I put it out of my hands ) edit : I fixed the code so it shows proper temperature.
I put the proximity sensor on A0 and tried grove_80cm_infrared_proximity_sensor.py ( http://prntscr.com/b3xl2q ) and grove_analog_read.py ( http://prntscr.com/b3xm00 ). I know they are essentially doing the same thing. I tried in different lightning environments and with different objects.
Collision sensor seems to be giving the same output on grove_analog_read.py ( http://prntscr.com/b3xo03 ), always ! And this is what I get as a result of grove_collision_sensor.py ( http://prntscr.com/b3xp5n ). Note that on the analog_read it’s connected to A0 and when i’m using grove_collision_sensor.py it’s connected to D2 port.
Hey Groover,
Great to hear that the accelerometer and the temperature sensor are reading fine.
The proximity sensor should be giving analog readings as the distance changes. Since the reading on yours does not change a lot, I think it might be broken. Can you double-check that is is connected to the right port and try again.
The collision sensor gives a digital 1 momentarily when it detects a collision. Did you try a couple of time to see if the readings changed.
If the sensors don’t work at all then they might be broken. You should reach out to the distributor and ask for a replacement.
