ex1) Continuously H-resolution mode (ADDR = 'L')
ex2) One time M-resolution mode (ADDR = 'H')
① Send "Continuously H-resolution mode " instruction
② Wait to complete 1st H-resolution mode measurement.(max. 180ms.)
③ Read measurement result.
How to calculate when the data High Byte is "10000011" and Low Byte is "10010000"
The result of continuously measurement mode is updated.(120ms.typ at H-resolution mode, 16ms.typ at M-resolution
mode, 2.9ms.typ at L-resolution mode)
① Send "One time M-resolution mode " instruction
② Wait to complete M-resolution mode measurement.(max. 24ms.)
③ Read measurement result
How to calculate when the data High Byte is "00000001" and Low Byte is "00010000"
In one time measurement, Statement moves to power down mode after measurement completion. If updated result is
need then please resend measurement instruction.
