1. temperature and DC0-5Vvoltage computing relationship

  The product comes standard with 0~50℃/-20~80℃/-40~60℃ multi-range. The default range is 0~50℃. Users can modify the range by dialing the switch. For example, the range is 0~50℃, 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 is the calculated DC0-5Vvoltage value. The list of commonly used values is as follows:

DC0-5Vvoltage(V)	temperatureValue (℃)	Calculation Process
0	0.0	(50-0)*(0-0)÷(5-0)+0
1	10.0	(50-0)*(1-0)÷(5-0)+0
2	20.0	(50-0)*(2-0)÷(5-0)+0
3	30.0	(50-0)*(3-0)÷(5-0)+0
4	40.0	(50-0)*(4-0)÷(5-0)+0
5	50.0	(50-0)*(5-0)÷(5-0)+0

    As shown in the above formula, when measuring 2.5V, current DC0-5Vvoltage is 25℃。

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, 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 humidity value, and C is the calculated DC0-5Vvoltage value. The list of commonly used values is as follows:

DC0-5Vvoltage(V)	humidityValue (%RH)	Calculation Process
0	0.0	(100-0)*(0-0)÷(5-0)+0
1	20.0	(100-0)*(1-0)÷(5-0)+0
2	40.0	(100-0)*(2-0)÷(5-0)+0
3	60.0	(100-0)*(3-0)÷(5-0)+0
4	80.0	(100-0)*(4-0)÷(5-0)+0
5	100.0	(100-0)*(5-0)÷(5-0)+0

    As shown in the above formula, when measuring 2.5V, current DC0-5Vvoltage is 50%RH。
