Hello, I have been using raspi-sump for a few months and decided to add a second one for my yard sump. Unfortunately the sensor failed due to the moist conditions so i am trying to set up this new sensor and hooked it up as the old sensor was. Are there other resistor needed for this model of sensor or is it a different wiring setup?

SR04T right? Should be the same, as long as it has 4 pins. One caveat with this sensor is that it does not work for readings closer than 20cm's. Other than that it should be fine.

Great, I thought that might be the case however the first time I could not get a reading, so a very quickly made a short cable to test with. I got it to work with one of the other sensors (the one you originally recommended) so the pi and cables checked out so I wired up the new sensor and the board got warm I'll grab some photos in the morning.

This is what I got:
