1. temperature and DC0-5Vvoltage computing
relationship
For example, the range is -30~80℃, the analog output is 0~5V DC0-5Vvoltage signal, temperature
and DC0-5Vvoltage The calculation relationship is as shown in the formula: C = (A2-A1) * (X-B1) / (B2-B1)
+ A1, where A2 is temperature range upper limit, A1 is the lower limit of the range, B2 is DC0-5Vvoltage
output range upper limit, B1 is the lower limit, X is the currently read temperature value, and C isthe
calculated DC0-5Vvoltage value. The list of commonly used values is as follows:

As shown in the above formula, when measuring 2.5V,current DC0-5Vvoltage is55℃。
2. humidity and DC0-5Vvoltage computing relationship
For example, the range is 0~100%RH, the analog output is 0~5V DC0-5Vvoltage signal,humidity and
DC0-5Vvoltage The calculation relationship is as shown in the formula: C =(A2-A1) *(X-B1) / (B2-B1) + A1,
where A2 is humidity range upper limit, A1is the lower limit of the range, B2 is DC0-5Vvoltage outputrange
upper limit, B1 is the lower limit, X is the currently read humidity value, and C is the calculated
DC0-5Vvoltage value. The list of commonly used values is as follows:
DC0-5Vvoltage(V)
