DESCRIPTION: 
The CS490000 is a single chip relative humidity and temperature multi sensor module comprising a calibrated digital output. Application of industrial CMOS processes with patented micro-machining (CMOSens® technology) ensures the highest reliability and excellent long term stability. The sensor head is connected to the pins by a small bridge to minimize heat conduction and response time. All pins are gold plated to avoid corrosion even under the harshest operating conditions. The device includes a capacitive polymer sensing element for relative humidity and a band-gap temperature sensor. Both are seamlessly coupled to a 14-bit analog to digital converter and a serial interface circuit on the same chip. This results in superior signal quality, a fast response time and insensitivity to external disturbances (EMC) at a very competitive price. Each CS490000 is individually calibrated in a precision humidity chamber. The calibration coefficients are programmed into the sensor's non-volatile memory. These coefficients are used internally during measurements to calibrate the signals from the sensors. The 2-wire serial interface and internal voltage regulation allows easy and fast system integration with a C Stamp^TM. Its tiny size and low power consumption makes it the ultimate choice for even the most demanding applications. The Sensor is compatible with the C Stamp microcomputer’s supplies and signal levels. Communicating with the Sensor is made easy with A-WIT's supplied software command HUMSIN. This simple one command interface is all that is required to setup and acquire Relative Humidity, Temperature, and Dew Point readings from the Sensor.
