I reversed the power input. caught the mistake within 5 seconds, disconnected. now the amber detection light stays on always. did i fry it?

Hello! You can try to adjust the potentiometer on the back of the sensor (turn it clockwise to decrease the sensitivity), it may be that the sensitivity is too high, causing the detection light to stay on.

can this be used with a 24vt power supply to power a light bar? needing repeat motion detection in a warm enviroment 100-118 degrees

No, max voltage is 5V. Also the output would not drive a LED light bar. You would have to use a relay.

Is there any way to disable the visible light on it?

hi, friend This product cannot disable visible light. Sorry, it did not help you! Sincere regards!

Battery power is better then mains power?? Am i understanding the product info correctly?

Hello! The working voltage of this product is: 3.3V/5V, which is generally connected to the power supply interface of the single-chip main board, and the single-chip main board is responsible for the power supply. Generally, the output voltage of the single-chip main board is 3.3V/5V.
