Using the data sampling principle of IC temperature and humidity, temperature and humidity sensitive devices, once again through Wen Min's specific algorithm, with the temperature and humidity changes, temperature and humidity compensation nonlinear impedance characteristics, linearity correction, calibration, making its temperature, humidity sensitive devices The non-linear resistive impedance characteristic translates into a linear analog output. Full range of temperature compensation Appearance digital calibration The temperature and humidity measurement range is high and the humidity measurement accuracy is high. Powerful, cost-effective Usage: Instrumentation, electrical equipment, air conditioning equipment, homes, factories, warehouses, humidification and drying equipment, meteorology and industrial automation and other fields.
