Connecting additional 1-Wire Devices
Posted: Wed Jun 08, 2011 10:08 pm
Hi,
I have temp and humidity 1 wire sensors and I'd like to connect these to the reef angel. It looks like it should be possible, anything I should be aware of? I know I'll have to dive into the 1-wire libaries which I haven't looked at yet.
Also I have some 1-wire temp sensor using the DS18B20 which have vcc and ground tied together. ( I bought them for another project but never needed them) I've tried connecting the Data line to the middle connector and the Vcc/GND to the ground (pin 3). Assuming I've read It looks like this should work and the temp setup page in the default program sees the sensor but I get a temp readings of 262 F. The DS18B20 data sheet shows an example where Vcc and GND are tied together. Any ideas? It isn't worth a lot of work to try to get these sensors working but I'd like to.
Thanks
Mike
