Grove - Temperature & Humidity Sensor Pro

Post by RNKot » Mon Feb 27, 2012 8:21 pm

I've bought 7 Grove - Temperature & Humidity Sensor Pro
http://www.seeedstudio.com/depot/grove- ... th=144_147
for my vivariums
all are installed in Grove - Base Shield
http://www.seeedstudio.com/depot/grove- ... th=132_134
controlled by Arduino UNO
i'm displaying tempereture & humidity via Grove - Serial LCD
http://www.seeedstudio.com/depot/grove- ... th=163_164
all goes correct expect one little thing: Grove - Temperature & Humidity Sensor Pro is not working further than 120cm. Sensor works in about 80cm but any cable further to 120cm doesn't work. The cables itseft are Ok - tested with Grove - Serial LCD.
What's the problem?

So what's the problem that Grove - Temperature & Humidity Sensor Pro is not working on length more than 100cm ?

Did you use a shielded cable?

Yes. It's ethernet cable. Grove - Serial LCD works on this cable at any length, same to clock module, but not the Sensor.
