HL3-1X photocells on all day speed trap test

Today's objective was to use the cells at a site with reasonable speeds to test battery life and taking and transmitting pulses in rapid succession.

So we took the cells to the highway next to the office and set them up.

Handy to have the guardrails so we could pretend it was a speedway.

60-90kmh average speed on this road.

Wanted to record over 1000 passages. Trap was set up for 9 hours.

Had some brief rain showers but mainly clear all day.
