Research of radiosonde humidity sensor with temperature compensation function and experimental verification

This paper presents the chip design strategy of resistance type humidity readout circuit for greenhouse application. The designed chip includes resistance change type humidity readout circuit, temperature compensation circuit, low voltage dropout generator (LDO), and analog to digital convertor (ADC).The humidity sensor which used in this research is HCZ_H8, and it is produced by Ghitron Company .Because resistance change type humidity sensor depends much on the temperature, so this paper develops a temperature sensing circuit to compensate the effects caused by the temperature change. The ADC in this research is13-bit fully-differential incremental delta sigma A/D converter, and the power supply is 3.3v, but the power supply of the humidity readout circuit is 5v, so a low voltage dropout generator (LDO) is included to match the power supply.

Compensation Function

Thermal error of machine tool is the main in total machine tool error, and obviously impairs the accuracy of the machined workpieces. Ram is a very important component of heavy-duty floor type boring-milling machine, and its thermal deformation is a significant source causing errors in machining process. Aiming at the thermal elongation of heavy type milling boring machine tool ram, the machine tool thermal errors are measured and compensated. Temperature compensation function in NC system is applied. Experiment results shows that 90% ram positioning error can be compensated.
