What are the applications of digital temperature and humidity sensors?
This device has a wide range of applications. Because it has its display and is moisture-proof, it is often used as a greenhouse indoor digital temperature and humidity sensor. Besides, it can also be used in communication rooms, warehouse buildings, and automatic control, and other places that require temperature monitoring.

How to calculate analog output?

1. Current output signal conversion calculation
For example, the range is -40~+80℃, 4~20mA output, when the output signal is 12mA, calculate the current temperature value. The span of this temperature range is 120℃, expressed by 16mA current signal, 120℃/16mA=7.5℃/mA, that is, 1mA current represents a temperature change of 7.5℃. The measured value is 12mA-4mA=8mA, 8mA*7.5℃/mA=60℃. 60+（-40）=20℃, the current temperature is 20℃.
2. Voltage output signal conversion calculation
For example, the range is -40~+80℃, 0-10V output, when the output signal is 5V, calculate the current temperature value. The span of this temperature range is 120℃, expressed by a 10V voltage signal, 120℃/10V=12℃/V, that is, a voltage of 1V represents a temperature change of 12℃. The measured value is 5V-0V=5V, 5V*12℃/V=60℃. 60+（-40）=20℃, the current temperature is 20℃.
