T1 Hall Probe System
10 Using your own software
The web interface of the T-1 allows computers, tablets and phones running different operating
systems to communicate and take data. It also allows simple connection to other software
running on those devices. The JSON format can be used to import data. In Python this could be
done as follows to create a floating point value "vala".
# IP address of T1.
ipaddr =
"192.168.1.135"
t1_ip = "http://"+ipaddr
# Get field data from T1 html server
ra = requests.get(t1_ip+"/io/t1/probe/field/value.json")
# Convert from text to float
vala = ra.json()
