Hi everyone
I am trying to follow the puck.js power meter example. Have a question about LDRs and battery life.
I have the below LDRs available at the local store. Which one would be the best for battery life?
Also, how to estimate, how long will the battery last for? Is the main power usage during the transmission?
Light resistance: 450K-1.2M
Dark resistance: 10MΩ
Light resistance: 135K-420K
Dark resistance: 10MΩ
Light resistance: 45kΩ - 140kΩ
Dark resistance: 10MΩ
Light resistance: 5kΩ-10kΩ
Dark resistance: 0.5MΩ
