We have used these for years without the transmitter, directly wired to a 5v input to measure available light. They are inexpensive and dependable.
Pros: Good value

I have used these sensors for a long time and they have always been very stable and reliable. If you are using this with a ST-O(x) housing you will need at least 1 3/4" to 1/2" bushing for the light sensor to mount in the box.
My Favorite Feature Easy to install / change out.
Yes, I recommend this product.
