Humidity and Temperature Sensor Qualified to Automotive AEC-Q100 Requirements

July 19, 2010 By Randy Frank

Many environments require special qualification testing to prove that the product can withstand more than usual application requirements. This can include Underwriters Laboratories (UL), International Electrotechnical Commission (IEC) or in the case of automotive, the Automotive Electronics Council (AEC).

Sensirion’s SHT21 humidity and temperature sensor has passed rigorous AEC Q100 qualification testing. The capacitive type humidity sensor and an improved band gap temperature sensor are Implemented in a standard semiconductor fabrication process.  Sensirion’s CMOSens technology enables the sensor component to be combined with the analog and digital signal processing circuitry. As a result, the output of the SHT21 can be either digital I2C, analog pulse width modulated (PWM) or analog Sigma Delta Modulated (SDM) format.

An evaluation Kit EK-H4 is available for the SHT21.
