Responds to white light. Detects upto 10,000 Lux (50 mW/cm2) within a 180°-wide cone field of view. See this videoclip
for a demo !
Application examples
- Measure room or ambient lightning.
- Put fish in a bowl with lights below and let the fish shadows play music (fish not included).
- Combine with the Air sensor and
Hot&Humid to create a full-blown climate control system.
Add Switches
to control water valves.
