    Its the same picture!

    You are going to need to be more specific with your query, for a starters what exactly are you trying to achieve with this sensor?

    Delete TR1 through TR3, the LEDs, and their driver. Tie the counter's o/p to the micro's data bus via some gates. Strobe the gates from the micro when you want to access the counter value.
