Light Sensor interface for data logger


1. Hobo Pendant Event Data Logger (UA-003-64) (Logger)

2. Hobo Pendant Optic USB Base Station & Coupler (BASE-U-1) (Coupler)

3. Island Research Passive Infrared Tracker Counter (Counter) ([url removed, login to view])


To link the Counter to the Logger without penetrating the Counter’s casing. The Counter is a sealed unit.


The counter has a red LED that flashes each time a count is recorded. A sensor to detect the light would provide an elegant solution.


A circuit casing has been milled to fit into the Counter, but can be modified depending on circuit size.

A trial with a photodiode was partially successful but not useful. The photodiode is sufficient to record an event if exposed to daylight, but was not sensitive enough to detect the Counter LED.


What is an estimate to have a circuit designed and a proof of concept circuit built?
