Help! Sound sensor return ping '0' when connected temperature sensor

Hi
I have a school project to measure the effect of temperature on the speed of sound.

Parts used:
HC-SR2014 Ultrasonic ranging sensor
MLX90614ESF-AAA temperature sensor

When I test them separately it works, but once I combine them on the same bread board. The sound sensor return "0" when I ping.

please assist.
1.How do I check whether is it a power problem?
2. If it is connection error, it will not work separately, right?

Please assist.

Post a schematic of your setup and the code you are using. From the information provided all I can say, with certainty, is that something is wrong.
