DC Voltage + current sensorS + temperture

HI

fuys i am looking for:
DC voltage sensor(0-50) with good accuracy.

second :

for AC current i am using YHDC SCT-013-000 Current Transformer but i did not try it for DC
is it work foR DC either (sorry iam a little newbi and scary to try ).

if not do you recommend any thin like it i need DC clamp current sennsor.

thank you.

other thing for inter face the current CT sensor with the arduino board can we use input jack .

if yes which one the 8 inc ?

last thing : i need temperture sensor to the range (15-30) dgree.
