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。
