The characteristics of these sensors are as follows:-

1, Temperature Sensor
A bandgap semiconductor sensor is used to measure temperature. This type of sensor is intrinsically linear and stable. It's main specifications include a temperature resolution of 0.01°C and a repeatability of 0.1°C.

2. RH Sensor
The RH sensor uses a capacitance polymer sensing element similar to those used in other water vapour flux instruments. However, the close integration of the sensing element and the signal processing electronics has enabled the manufacturers to optimise the design for long-term stability, low hysteresis, high response speed, and an ability to recover from exposure to high humidity and contact with water without loss of calibration.

The chip is fabricated using novel CMOSens™ technology that integrates the sensors with signal processing electronics and digital output conversion. Each chip is individually calibrated by the manufacturer in a precision humidity chamber, with the calibration constants stored on-chip. Biox measures an additional calibration correction, to ensure the highest performance in water vapour flux measurement.
