Connection of relative humidity and temperature sensors.
Example 2.
Memory capacity calculation
Let’s assume we measure and store data from channels AIN1, AIN2 and DIN1 every 5
minutes. Now calculate how many bytes will take one record:
Date – 4 bytes
Time – 4 bytes
AIN1- 4 bytes
AIN2 – 4 bytes
DIN1 – 4 bytes
Together it is 20 bytes for one record. Internal memory capacity is 128kB (about 131000
bytes) and therefore we can store
131000/20=6550 records
Every 5 minutes record will make 12 records per hour. Nr. of recorded hours:
6550/12=545 hours and it is about 22 days (more than 3 weeks).
