When I ran the demo code "tmp007" downloding from the website (https://github.com/adafruit/Adafruit_TMP007_Library) using Arduino UNO, both of the sensors returned lines as below.
"Adafruit TMP007 example"
"No sensor found"
But today, one of the sensors returned lines;
"Adafruit TMP007 example"
"test".
In both cases, I cannot obtain any temperature data.
I have already checked that
-resistance between sensor board and UNO is less than 2 ohm for each of wires of VCC, GND, SDA and SCL,
-voltage between VCC and GND is 5V on sensor board,
-the demo code was succesfully written to the board.
Attached are photos of sensor board and end of the each wire.

Could you tell me how to check and solve our problem?
